Question

What procedure would you use to find 2/3 / 7/9

a. Multiply the first fraction by the reciprocal of the second fraction.
b. Multiply the second fraction by the reciprocal of the first fraction.
c. Multiply by the least common multiple of 3 and 9.
d. Multiply by the greatest common factor of 3 and 9.

Answer 1

a. Multiply the first fraction by the reciprocal of the second fraction.

Explanation:

Alrighty.

So we have

2/3 ÷ 7/9

We are going to find the reciprocal (by flipping the numerator and denominator) of the second fraction. Sooo..... 7/9 would actually be 9/7

so now we're doing:

2x9 ÷ 3x7 = 18/21 which can simplify too!

So the Final Awnser is: 6/7

(checked with calculators multiple times thank you very much.)
