Question

By what number -55/18 be divided to get 22/9

Answer 1

Solution :

Let, the number by which (- 55/18) is to be divided to get 22/9 be x

Then,

(- 55/18) / x = 22/9

or, 22/9 * x = - 55/18

or, x = - 55/18 * 9/22

or, x = - (11 * 5)/(2 * 9) * 9/(2 * 11)

or, x = - 5/(2 * 2)

or, x = - 5/4

∴ the required number is (- 5/4).
