Question

If a:b=2:3 and b:c= 4:5, the ratio a:b:c is equal to​

Answer 1

Answer:

a:b:c = 8:12:15

Step-by-step explanation:

a:b = 2:3

b:c = 4:5

$\frac{a}{b} = \frac{(2 \times 4)}{(3 \times 4)} = \frac{8}{12} \\ \frac{b}{c} = \frac{(4 \times 3)}{(5 \times 3)} = \frac{12}{15}$

Now,

a:b = 8:12

b:c = 12:15

So,

a:b:c = 8:12:15
