Question

Determine whether the following number are in proportion
1.2, 2.7, 0.4, 0.9

Answer 1

Answer:

Extreme terms = 1.2 and 0.9

Mean terms = 2.7 and 0.4

Product of extreme terms = Product of mean terms

1.2 × 0.9 = 2.7 × 0.4

1.08 = 1.08

L.H.S = R.H.S

Hence, 1.2, 2.7, 0.4 and 0.9 are in proportion.
