Answer 1

Answer:

Determine if the following are in proportion. If yes write them in proper form.

(i) 32, 48, 140, 210; (ii) 6, 9, 10 and 16

Solution:

(i) 32, 48, 140, 210

32 : 48 = 32/48 = 2/3 = 2 : 3

140 : 210 = 140/210 = 2/3 = 2 : 3

So, 32 : 48 = 140 : 210

Therefore, 32, 48, 140, 210 are in proportion.

i.e., 32 : 48 :: 140 : 210
