9. A/12 = 3/9 A = 4
10. 8/B = 12/21 b = 14
11. 24/36 = c/15 c = 10
12. 27/6 = 18/d d = 4
13. 7/8 = e/56 e = 49
14. 27/36 = 6/f f = 8

Iam assuming you want to know if
the ratios are true.
Reduce each fraction to the lowest term
and compare them by inspection:
9. 4/12 = 3/9.
Divide the numerator and denominator
of the first fraction by 4.
Divide the numerator and denominator
of the 2nd fraction by 3.
RESULTS: 1/3 = 1/3.
10. 8/14 = 12/21, 4/7 = 4/7.
11. 24/36 = 10/15 , 2/3 = 2/3.
Try doing the others.
