Question

the value a:c from the following proportion a:b=2:3 and b:c 4:5 is

Answer 1

a:c is equal to 8:15. In the question, it is given that the ratio of a to b is 2:3 and that of b to c is 4:5

Answer 2

Answer:

8 : 15

Step-by-step explanation:

b : c =4 :  5

=> b = $\frac{4}{5} c$

$\frac{a}{b} =\frac{2}{3}$

=> a = $\frac{8}{15} c$

$\frac{a}{c} = \frac{8}{15}c : c$

$\frac{a}{c} =\frac{8}{15}$
