1/7 / 4 as a fraction

Answers

1/7/4 is a fraction.

1/7 divided by 4 is equal to 1/28.

Given that a fraction, we need to make it in proper fraction,

To divide fractions, you need to follow a specific rule. To divide one fraction by another, you multiply the first fraction by the reciprocal of the second fraction.

The reciprocal of a fraction is obtained by interchanging the numerator and the denominator.

In this case, you have the fraction 1/7 divided by 4. To find the result, we can express 4 as a fraction with a denominator of 1: 4 can be written as 4/1.

Now, we can multiply the first fraction (1/7) by the reciprocal of the second fraction (4/1):

(1/7) x (1/4)

To multiply fractions, you simply multiply the numerators together and the denominators together:

(1 x 1) / (7 x 4)

The result is:

1/28

Therefore, 1/7 divided by 4 is equal to 1/28.
