Answer:
Step-by-step explanation:
If the ratio of first to the second is equal to ratio to third to the fourth, these will be in proportion
S.no Problem First to second ratio third to fourth ratio Yes/No
a) 15, 45, 40, 120 15 /45 = 1:3 40 /120 = 1:3 Yes
b) 33, 121, 9, 96 33/121 = 3:11 9/96 = 3:23 No
c) 24, 28, 36, 48 24/28 = 6:7 36/48 = 3:4 No
d) 32, 48, 70, 210 32 /48 = 2:3 70/210 = 1:3 No
e) 4, 6, 8, 12 4/6 = 2:3 8/12 = 2:3 Yes
f) 33, 44, 75, 100 33/44 = 3:4 75/100 = 3:4 Yes
