Find the answer. Hope you understand .​

Answer 1

Step-by-step explanation:

7. 2/3 + -4/5 + 1/3 + 2/5

= 2/3-4/5+1/3+2/5

= 10-12/15+5+6/15

= -2/15+11/15

= -2+11/15

= 9/15

= 3/5

8. Sum = 5/9

One no. = -7/8

Let the other no. be x

By condition,

x + -7/8 = 5/9

x-7/8 = 5/9

x = 5/9+7/8

x = 40+63/72

x = 103/72

x = 1 31/72

Answer 2

7.

2/3-4/5+1/3+2/5

= 10-12+5+6/15

=9/15

=3/5

8.

-7/8+X=5/9

X=5/9+7/8

X=40+63/72

X=103/72
