Question

sum of two rational number is 1 if one of them is 4 upon5 then find other is​

Answer 1

Answer:

let the numbers be x and y.

So, ATQ

x+y=1

and

x=4/5

Replacing the value of x in above equation.

$\frac{4}{5} + y = 1 \\ y = 1 - \frac{4}{5} \\ y = \frac{5 - 4}{5} \\ y = \frac{1}{5}$

So, other number is 1/5.
