Question

please solve this equation it's urgent ☺️​

Answer 1

Answer:

let the no. be x, then

3/20+ x = 4/7

x = 4/7 - 3/20

x = 59/140

Answer 2

let the other rational number be x

A.T.P.

$\frac{3}{20} + x = \frac{4}{7}$

•°•

$\frac{3 + 20x}{20} = \frac{4}{7}$

$7(3 + 20x) = 4(20)$

$21 + 140x = 80$

$140x = 80 - 21$

$140x = 59$

$x = \frac{59}{140}$

•°• the another rational number is 59/140
