Question

Find the quotient 3 6/7 divided by 5/21

Pls explain bc I’m having finals and I need a bit more help with this

Answer 1

81/5 or 16 1/5.

Explanation:

First convert the mixed number to an improper fraction:

3 6/7

= (3*7 + 6) / 7

= 27/7.

So we have

27/7 / 5/21

Invert the second fraction and multiply:

= 27/7 * 21/5

= (27*21) / (7*5)

= (27*3) / 5 ( as 21/7 = 3)

= 81/5

= 16 1/5.
