To Find:

\mathbf{\textrm{Find compound ratio of }\dfrac{a}{b}\ and\ \dfrac{c}{d}}Find compound ratio of

b

a

and

d

c

Solution:

Compound ratio of two fraction is obtained by multiplication of two fraction:

\mathbf{\textrm{ Compound ratio }=\dfrac{a}{b}\times \dfrac{c}{d}} Compound ratio =

b

a

×

d

c

\mathbf{\textrm{ Compound ratio }=\dfrac{5}{7}\times \dfrac{2}{9}} Compound ratio =

7

5

×

9
