Solve (9/5) / (72/7)
First: rule - you can't divide fractions. multiply the 1st fraction with the reciprocal of the 2nd fraction (flip the 2nd fraction).
(9/5)(7/72)
Sec: combine the numerators & denominators.
(9*7)/(5*72)
63/360
Third: simplify the fraction into lowest terms - find a number divisible with the values which is, 9.
7/40

Since you are dividing and simplifying, try to see if you can simplify from the beginning.
Change the division to multiplication first.
9 7
--x--
5 72
Now try to see if you can simplify the diagonal numbers. You are able to simplify 9 and 72. Now you have:
1 7
--x--
5 8
Now you just have to complete the multiplication.

9/5 / 72/7
When you divide with fractions, you find the recipricol of the 2nd number, thus:
9/5 x 7/72
63/360
The common factor is 9. Divide 63 by 9 and 360 by 9.
Thus: 7/40

= (9/5)/(72/7)
= 9/5 * 7/72
= (9 * 7)/(5 * 72)
= 63/(5* 72)
= 7 / 40.
