What Does 3/4 Divided by 21 Mean?

The expression "3/4 divided by 21" refers to the mathematical operation where the fraction 3/4 is divided by the whole number 21. To understand this better, we need to grasp the underlying principles of division and fractions. Dividing a fraction by a whole number is a common mathematical task that requires the application of specific rules.

How Do You Perform the Division of 3/4 by 21?

To divide "3/4" by "21," we can use the following steps:

Rewrite the division of a fraction by a whole number as a multiplication problem.
Change the whole number into a fraction by expressing it as a fraction with a denominator of 1.
Multiply the first fraction (3/4) by the reciprocal of the second fraction (1/21).

So, the operation can be rewritten as:

3/4 ÷ 21 = 3/4 × 1/21

Now, let's perform the multiplication:

What is the Result of 3/4 Divided by 21?

When you multiply the fractions, you perform the operation as follows:

(3 × 1) / (4 × 21) = 3 / 84

This result simplifies to:

3/84 = 1/28

Thus, "3/4 divided by 21" simplifies to "1/28." This means that if you take three-quarters of a whole and divide it evenly among 21 parts, each part would represent 1/28 of that whole.

Why is Understanding 3/4 Divided by 21 Important?
