P% = 0.5 * 100 = 50%

Ex: WHAT minus P% is Y?

What minus 2% is 490?

X minus 2% is 490

X = Y/(1 - P%)

X = 490/(1 - 2%)

p = 2%/100 = 0.02

X = 490/(1 - 0.02)

X = 490/0.98

Percentage Change Formula

Percentage Change = [ (New_Value - Original_Value) / |Original_value| ] * 100

Ex: Percentage Change from 250 to 350?

Solution: New_Value = 350, Original_Value = 250

Substitute the given values in the formula.

Percentage Change = (350 - 250) / |250| * 100

Percentage Change = (100/250) * 100 = (2/5) * 100 = 0.4 * 100

Percentage Change = 40%

∴ Percentage Change from 250 to 350 is 40%

Percent Error Formula

percent error = [ (AV - OV) / | AV | ] * 100%

where: AV is the actual value, and OV is the observed value.

Ex: Percent Error from 200 to 250?

Solution: actual value = 200, observed value = 250

Percent Error = [ (AV - OV) / | AV | ] * 100%

Percent Error = (250 - 200) / |200| * 100

Percent Error = (50/200) * 100 = (1/4) * 100 = 0.25 * 100

Percent Error = 25%

∴ Percent Error from 200 to 250 is 25%

Percentage Increase Formula

Percentage Increase = [ (FV - SV) / | SV | ] * 100%

where: FV is the final value, and SV is the starting value.

Ex: Percent Increase from 90 to 108?

Solution: Starting Value = 90, Final Value = 108

Percentage Increase = (108 - 90) / |90| * 100

Percentage Increase = (18/90) * 100 = (1/5) * 100 = 0.2 * 100

Percentage Increase = 20%

∴ Percent Increase from 90 to 108 is 20%

Percentage Decrease Formula

Percentage Decrease = [ (SV - FV) / | SV | ] * 100%

Ex: Percent Decrease from 80 to 68?

Solution: Starting Value = 80, Final Value = 68

Percentage Increase = [ (SV - FV) / | SV | ] * 100%

Per. Decrease = (80 - 68) / |80| * 100

Per. Decrease = (12/80) * 100 = (3/20) * 100 = 0.15 * 100

Per. Decrease =

∴ Percent Decrease from 80 to 68 is 15%

Percentage Difference Formula

Percentage Difference = 100 * |a - b| / ((a + b) / 2)

Ex: Percent Difference from 300 to 200?

Solution: a = 300, b = 200

Percentage Difference = 100 * |a - b| / ((a + b) / 2)%

Percentage Difference = 100 * |300 - 200| / ((300+200) / 2)%

P.D = 100 * |100| / (500/2)

P.D = (10000 / 250)%

∴ Percent Difference from 300 to 200 is 40%

Percentage of a Percentage Formula

Percentage of a Percentage = (pct1 ÷ 100) × (pct2 ÷ 100) × 100

where: pct1 is the percentage 1, and pct2 is the percentage 2.

Ex: Find 25% of 60%

Solution: pct1 = 300, pct2 = 200

p = (pct1 ÷ 100) × (pct2 ÷ 100) × 100

p = (25 ÷ 100) × (60 ÷ 100) × 100

p = .25 × .6 × 100

p = .15 × 100

∴ 25% of 60% is 15%

Doubling Time Formula

doubling time = log(2) / log(1 + r)

Where: r = a constant growth rate

Convert Fraction to Percentage

Simple Formula to Convert Fraction to Percent

(n / d) * 100 = P

where n is the numerator, d is the denominator, and p is the percentage.

Diamond Problem Calculator

What is a diamond problem diamond math problems, how to do diamond problems case 1: given two factors, case 2: given one factor, and the product or sum, case 3: given product and sum, while searching for factors, how to use diamond problem calculator.

Welcome to our diamond problem calculator, also known as a diamond problem solver . This intuitive tool allows you to enter any two numbers and the two others will appear. We've also prepared a compendium that answers all your burning questions about this topic.

Let's start by introducing what a diamond problem is and continue smoothly to some how to do diamond problems of various types tips. Are you ready?

Despite what you might think, the diamond problem doesn't have a lot in common with gemstones💎 or diamond rings💍 — though we can teach you how to calculate a diamond's weight . It is more closely related to what is often called a diamond in math ♦️ or cards🃏 - the rhombus, a quadrilateral shape. The diamond problem is a type of exercise that happens in a diamond shape 💠 - which we can also represent as a cross with 4 sections.

Diamond problems: common shapes of a task

So, what is the diamond problem in math ? It's where you fill in all four fields, related by some mathematical operation . The pattern of the numbers is constant:

Solving the diamond problem means that you know only two numbers out of four, and you need to find the missing ones . And that's all!

Cross with factors A on the left, B on the right, product in the top, and sum in the bottom

There are three main types of diamond problems, and the diamond problem calculator can deal with all of them. If you're wondering how to do diamond problems in each of these cases, scroll down to the next sections.

This is the easiest case: you have two numbers, A and B, and you need to find the sum and product of them. For example, let's say that we want to solve the diamond problem for factors 13 13 13 and 4 4 4 :

Resolution of a probelm with diamond

You might meet this type of a diamond math problem in the first lesson about the diamonds - when your teacher first introduces the concept.

Let's have a look at a slightly more complicated case, where you have one of the basic numbers, and a product or a sum. The first thing to do is to calculate the factor missing from the diamond. Transform your equation is such a way to solve for the unknown value:

a) When you're given one factor and the sum , you can find a second factor by a simple subtraction:

Setup of a problem with diamond

With both factors in hand, simply multiply them to get the last number: product = 5 × 6 = 30 = 5 \times 6 = 30 = 5 × 6 = 30 .

Cross with factors 5 on the left, 6 on the right, product 30 in the top, and sum 11 in the bottom

b) If you know one factor and the product , divide the product by the factor to find the second product:

Cross with factors 9 on the left, and product 63 in the top

Then calculate the sum , use the following expression: sum = factor  A + factor  B = 9 + 7 = 16 = \text{factor}\ A + \text{factor}\ B = 9 + 7 = 16 = factor   A + factor   B = 9 + 7 = 16 .

Cross with factors 9 on the left, 7 on the right, product 63 in the top, and sum 16 in the bottom

Remember, you can always quickly solve these diamonds or verify your answers with our diamond problem calculator.

Now we're coming to the last issue and the most common diamond problem: the case where you know the sum and the product of the two numbers, but you don't actually know the numbers themselves.

This type of diamond math problem is helpful when you're learning about factoring a quadratic equation. Why?

Let's say that we have a quadratic equation:

We would like to factor this equation, meaning that we'd like to present it in a form:

How to find these numbers - the roots of the quadratic equation ? You know that their product must be equal to 12 12 12 , and that their sum is equal to 7 7 7 . And that's exactly what you're trying to find out in the diamond problem! 🙂 You can rewrite this question in the form of a diamond:

Cross with question marks on the left and right,product 12 in the top, and sum 7 in the bottom

How to solve such a problem?

Don't forget the negative numbers:

And here it is! We can stop here, as we've found the two numbers which meet the condition 🎉
