Question

1. Check if the following are in proportion or not. 1)27, 72, 45, 120 2)33, 99, 51, 153 3)12, 14, 4, 7 4)100, 200, 2000, 1000 5)9, 18, 23, 46​

Answer 1

Answer:

1)25,72,45,120

= 25/72 = 45/120

= 3/8 = 3/8

Therefore 25, 72,45,120 are in proportion

2)33,99,51,153,

= 33/99 = 51/153

= 1/3 = 17/51

Therefore 33,99,51,153 are not in proportion

3)12,14,4,7

= 12/14 = 4/7

= 6/7 = 4/7

Therefore 12,14,4,7 are not in proportion

4)100,200,2000,1000

= 100/200 = 2000/1000

= 1/2 = 2/1

Therefore 100,200,2000,1000 are not in proportion

5)9,18,23,46

= 9/18 = 23/46

= 1/2 = 23/46

Therefore 9,18,23,46 are not in proportion

I'm not sure if this is correct but I hope it helps!
