Question

by what number should (1/2)^-1 be divided so that the quotient is (-5/4)^-1

Answer 1

we know that
divident = (divisor * quotient) + remainder
here
divident = (1/2)^-1 = 2
quotient = (-5/4)^-1 = -4/5
remainder = 0
so
2 = (divisor * (-4/5))+0
2 = divisor * (-4/5)
divisor = (-2*5)/4
divisor = -5/2

Answer 2

Answer:

-5/2

Step-by-step explanation:

we know that

divident = (divisor * quotient) + remainder

here

divident = (1/2)^-1 = 2

quotient = (-5/4)^-1 = -4/5

remainder = 0

so

2 = (divisor * (-4/5))+0

2 = divisor * (-4/5)

divisor = (-2*5)/4

divisor = -5/2
