Answer:

The sum of rational numbers are x +y=3/8,one of them are 2/5 =y then other number is x

Step-by-step explanation:

x+y=3/8

x+2/5=3/8

x=3/8-2/5

x=(3×5)/8×5-(2×8)/8×5

x=15/40-16/40

x=15-16/40

×=-1/40

Hope this helps you

Answer 2

Answer:

1/40

Step-by-step explanation:

2/5 + x = 3/8

x= 3/8-2/5

we need to find common denominator

x=3/8*5/5= 15/40

x=2/5*8/8= 16/40

16-15=1

therefore,16/40-15/40=1/40
