Question

If A:Bv= 3: 2 and b:C = 4:5 find A : C .
​

Answer 1

Step-by-step explanation:

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. With this information we have to calculate a:c.

Let’s see, how can we do it.

\begin{array}{l}{\Rightarrow \frac{a}{b}=\frac{2}{3}-(i)} \\ \\ {\Rightarrow \frac{b}{c}=\frac{4}{5}-(i i)}\end{array}

By multiplying the equation (i) and (ii), we get,

\Rightarrow \frac{a}{b} \times \frac{b}{c}=\frac{a}{c}=\frac{2}{3} \times \frac{4}{5}=\frac{8}{15}

Therefore, a:c is equal to 8:15.

We have used the concept ratio and proportions here. It is a simple way to solve questions involving ratio. Other questions that involve ratio in it can be solved in the similar manner.
