Answer 2

11.Reciprocal of 4 /5 is 5/4
so ,2/3+5/4
A/q
2/3 +5/4 =8+15/12
=23/12answer
12.The multiplicative inverse of 22/39 is 39/22
so ,11/13 × 39/22
a/q
11/13 × 39/23
=3/2
13.let the no. be x
A/q
-7/11 × x=1
x=1 ÷ (-7/11)
=1 × 11/7
=11/7 answer☺
let's check-
-7/11 × -11/7 = 1
1 =1
LHS =RHS PROVED
14.let the no. be x
-5/7 + x = 0
x =0 - 5/7
= 5/7
let's check
-5/7 + 5/7= 0
0 = 0
LHS=RHS PROVED☺
15.[1/3 × (-3/4)] × -8/9 = 1/3 × (-3/4 × -8/9 )
-1/4 × 8/9 = 1/3 × -2/3
-2/9 = -2/9
HOPE ITS HELPS YOU☺☺
