Question

By what rational should -75/4 be divided to get -25/8.

Answer 1

Answer:

Let the rational number be 'x'

x = 75 ÷ 25 = 75 × 8 = 3 × 2 = 6

4 8 4 25

Answer 2

Step-by-step explanation:

Let us consider, the divisor be x

-75/4 ÷ x = - 75 / 4 × 1/x

= -75/4x

x = 18.75

We need the answer in rational form. Let's rationalize the obtained number,

Let y = 18.75

= 100y = 1875........(Multiplying both sides by

100)

= 100y - y = 1875 - 18.75

= 99y = 1856.25

y = 1856.25/99

Therefore, -75/4 must be divided by 1856.25/99 to get -25/8
