Question

7. If a:b = 5:6 and b:c= 9:4, then find a : c.
​

Answer 1

Answer:

a=5 c=4 totally a:c = 5:4 ...........

Answer 2

Ans

• a:b - 5:6
• b:c - 9:4
• a:c - to find

$\frac{a}{b} = \frac{5}{6} \\ \frac{b}{c} = \frac{9}{4}$

Make the values of b alike in both the ratios.

$\frac{5}{6} \times \frac{3}{3} = \frac{15}{18 } \\ \\ \frac{9}{4} \times \frac{2}{2} = \frac{18}{8}$

With this the value of a:c can be found

$a - 15 \\ b - 18 \\ c - 8$

Then

a:c - 15:8
