-76/35

Step-by-step explanation:

the reciprocal of -7/4 and 2/9 are -4/7 and 9/2

-4/7×9/2=-18/7

-18/7+2/5(additive inverse of -2/5 is 2/5)

LCM=35

so,

-90/35+14/35

-76/35

2. Step-by-step explanation:

The additive inverse of 2 is -2. In general, the additive inverse of a number, x, is -x because of the following: x + (-x) = x – x = 0.
