Answer 1

Answer:

-16/5,13

Step-by-step explanation:

Let the number be x

(i) (-4/5)-³ ÷ x = (16/25)-²

(-5/4)³ ÷ x = (25/16)²

-125/16 ÷ x = 625/256

-125/16 × 1/x = 625/256

1/x = 625/256 ×-16/125

1/x = -5/16

x = -16/5

(ii) [(-1/2)-²+(-1/3)-²] ÷ [(1/5)-¹-(1/4)-¹]

[-2² + -3²] ÷ [ 5-4]

[ 4+9] ÷ 1
