10 Per Cent Of 30 Using this fraction calculator, it is possible to make a percentage count in three ways. So, we think you found us looking for answers to questions like these: 1) What is 10% of 30? 2) 3 is how many per cent of 30? Or maybe: How much is 10 per cent of 30?

## How To Calculate Percent – Step By Step

See the answers to the questions posed above:

### 1) How Much Is 10% Off 30?

To calculate this percentage, we suggest using this formula:

**Substituting the supplied values:**

10 / 100 = Part / 30

Performing Cross Multiplication:

10 x 30 = 100 x Part, or

300 = 100 x Part

Now it’s just divided by 100 and get the answer:

Part = 300 / 100 = 3

### 2) 10 Is How Many Per Cent Of 30?

Reuse the same formula:

% / 100 = Part / Total

Substituting the values:

% / 100 = 10 / 30

Performing Cross Multiplication:

% x 30 = 10 x 100

Divide by 30 and ache to answer:

% = 10 x 100 / 30 = 33.333333333333%

## How To Calculate 10% Off 30

In the store, the product cost €30, you remained given a 10% discount, and you want to understand how much you saved.

### Solution:

Saved Amount = Product Price * Discount Percentage/ 100

Amount saved = (10 * 30) / 100

Amount saved = €3

When you buy an item for €30 and the discount is 10%, you will pay €27 and save €3.

Precise and straightforward explanation to know how to calculate 10 per cent of the number 30. Check the calculation method and learn for the future.

To calculate 10 per cent of the number 30, we need to create a ratio from which we can quickly determine the value we’re looking for.

**We first create two simple equations by data we know.**

30 equals 100%, so that we can save that as 30 = 100%

The value we’re looking for can be called x

We know that x is 10 of the output value, so that we can write that as x = 10.

So we have two equations simple equations:

1) 30=100%

2) x=10%

## Once We Compare These Two Equations, We Get:

30/x=(100%)/(10%)

Now we have to solve the simple equation.

We calculate 10 per cent of 30 :

30/x=100/10

(30/x)*x=(100/10)*x

30=10*x

30/10=x

3=x

x=3

Today I’m successful in showing you how we use the rule of three!

In the rule of three, three values are wanted so that we discover the 4th value.

In this form, we will put on top the number that you want to take that percentage along with your rate, which will always be 100%.

Underneath, let’s put the percentage you want to find out, and on the side an X (which is the number corresponding to the rate, which is what you want to find out).

10% of 30

100% = 30

10% = x

Now, let’s cross multiply the 100% with the X and the 10% with the 30.

## What will stay:

100x = 10 * 30

100x = 300

Now, we pass the number that is with the X, which in this case is 100, to the other side. (Remember that the sign will reverse as it is going the other way, instead of multiplying, it will divide);

Using this online percentage calculator, it is possible to calculate percentages in three ways. So, we think you’ve found us looking for answers to questions like these:

1) What is 10 per cent (%) of 30? 2) 3 is how many per cent of 30? Or maybe: 10% of 30.

**See below for solutions to these issues.**

## How To Calculate Percentage – Step By Step

See the answers to the questions presented above:

### 1) What is 10% of 30?

We recommend using this formula:

% / 100 = Part / Whole

Substituting the given values, we have:

10 / 100 = Part / 30

Performing Cross Multiplication:

10 x 30 = 100 x Part, or

300 = 100 x Part

Now just divide by 100 and get the answer:

Part = 300 / 100 = 3

### 2) 10 is how many per cent of 30?

Use the same formula again:

% / 100 = Part / Whole

Substituting the values, we have:

% / 100 = 10 / 30

Perform Cross Multiplication:

% x 30 = 10 x 100

Divide by 30 and find the answer:

% = 10 x 100 / 30 = 33.333333333333%
