Question

The reciprocal of x is 0.25. The reciprocal of y is 10.

Work out the value of xy.

The book says the answer is 5/6 but I can’t get the same answer. Please help.

Answer 1

XY=2/5

Explanation:

Given the reciprocal of x is 0.25, that is then

x = 1/ 1/4 = 4

Given the reciprocal of y is 10 then

y = 1/10

xy = 4 ×1/10 =4/10 = 2/5
