Question

if 4:5 =y::20 then what will be the value of y?​

Answer 1

Answer:

Since 4:5 :: y : 20, we can write

$\frac{y}{20} = \frac{4}{5}$

$y = \frac{4}{5} \times 20$

$y = 16$

Hope it helps.

Answer 2

$\sf \frac{4}{5} = \frac{y}{20} \implies 4 \times 20 = 5 \times (y)$

$\sf y = \frac{80}{5} = 16$

• Value of y = 16
