Question

What shoul be added to -5\2 to get -7\5 Solve in rational number​

Answer 1

Let the required number be 'x'

x +(- 5/2) = (-7/5)

x-5/2 = -7/5

x = -7/5 + 5/2

x = -35 + 25

    ---------------

           10

x = -10/10

x = (-1)

Answer 2

Let the number be x
x+(-5/2)=-7/5
x-5/7= -7/5
x= -7/5+5/7
LCM=35
(-7*7/5*7)=-49/35
(5*5/7*5)=25/35
-49/35+25/35 = -24/35
Therefore x = -24/35
