Question

17. Find the compound ratios of 5 : 6 and 2:3​

Answer 1

Answer:

5/6 convert 5:6 and 2:3 2/3 ,,,

Answer 2

Answer:

2:3

Step-by-step explanation:

We have to find the compound ratio for the given pair of ratios.

Compound ratio =

a:b, c:d\\\\\text{Compund ratio} = \dfrac{a}{b}\times \dfrac{c}{d} = ac:bd

1) 5:6 and 2:3

\text{Compund ratio} = \dfrac{5}{6}\times \dfrac{2}{3} = \dfrac{5}{9} = 5:9

2) 14:9 and 1÷7:1÷3.

14:9, \frac{1}{7}:\frac{1}{3}\\\\\text{Compound Ratio} = \dfrac{14}{9}\times \dfrac{\frac{1}{7}}{\frac{1}{3}} = \dfrac{2}{3} = 2:3
