Question

6/15 divided by 4/21 = ?

Answer 1

Keep 6/15 the same and change Division sign into a multiplication sign and flip 4/21 and that will become 21/4. $\frac{6}{15}* \frac{21}{4}= \frac{126}{60}$ 126/60=21/10 and 21/10 as a mixed number is 2 1/10 so your answer is 2 1/10. Hoped I helped. :)

Answer 2

Keep Change Flip!
Keep the first fraction.
Change the divided sign to multiply sign.
Flip the second fraction
And you get 6/15 * 21/4 = 126/60 which simplified to 21/10 or 2 1/10.
So the answer was 2 and 1/10.
