Answer:
2) The required number is 140
3) The required number is -2/5
Step-by-step explanation:
2)
Let x be the required number
3x/5-2x/7 = 44
(21x-10x )/35 = 44
11x = 35 x 44
x = 35x4
= 140
3) (-5/4)⁻¹ = -4/5
(1/2)⁻¹ = 2
Let x be the required number
dividend = divisor x quotient + remainder
x = (- 4/5)/2 = - 2/5
