​

Answer 1

Let one number be x. Therefore, according to the question, the other number will be 2/5 times x, which is 2/5×x or 2x/5

According to the question:

x+(2x/5)=70

=)(5x+2x)/5=70

=)5x+2x=70×5

=)7x= 350

=) x = 350/7

=)x= 50

Therefore 2x/5 = (2×50)/5 = 100/5 = 20

Therefore the numbers are 50 and 20

Answer 2

let the no. be X then
the other is 2/5x
Here,

$x + \frac{2}{5} x = 70$
$5x + 2x = 350$
$7x = 350$
$x = 50$
then the no.s are 50 and 20..
