# What is 20% of 45?

## Finding the 20% of 45 With Decimal Method

To find 20% of 45, we first need to understand what percentage means. Percentage is a way of expressing a fraction or a portion of a whole as a fraction out of 100. So, 20% means 20 out of 100 or 20/100 as a fraction, which simplifies to 0.2 as a decimal.

Now, to find 20% of 45, we use the formula:

20% of 45 = (20/100) x 45

Here, we’re multiplying the decimal equivalent of 20% (0.2) by the number 45 to get the answer.

Simplifying the expression by multiplying the numerator and denominator by 5, we get:

20% of 45 = (20/100) x 45 = (1/5) x 45

Now, we can simplify this expression further by multiplying the numerator and denominator by 9:

20% of 45 = (1/5) x 45 = (1 x 9) / (5 x 9) x 45 = 9 / 45

Simplifying this expression, we get:

20% of 45 = 0.2 x 45 = 9

## Finding the 20% of 45 With the Help of Vedic Math

In this problem, we will use the Vedic Math technique of “vertically and crosswise” to find 20% of 45. Vedic Math is a system of mathematics that originated in ancient India and used various techniques and principles to solve problems efficiently.

### Here are the steps to find 20% of 45 using Vedic Math:

Step 1: Divide the number by 10 (move the decimal point one place to the left) to get 10% of 45, which is 4.5.

Step 2: Multiply 10% by 2 to get 20%.

10% x 2 = 4.5 x 2 = 9

### Therefore, 20% of 45 using Vedic Math is 9.
