Question

Deb has 3/4 of a brownie. She wants to divide it up into 1/4's of a brownie so she can have it throughout the day. How many 1/4's will she have?

Answer 1

3

Explanation:

3/4 ÷ 1/4 = ?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

3/4 × 4/1

For fraction multiplication, multiply the numerators and then multiply the denominators to get

3 × 4 / 4 × 1 = 12/4

Since 12 divided by 4 equals 3 then,

12/4 = 3

Therefore 3/4 ÷ 1/4 = 3
