Two times the reciprocal of a number equals 40 times the reciprocal of 50. Find the number

Let us assign "x" to represent the number.

Let us have 1/x to be reciprocal of a number.

Then we have:

2*1/x for the "two times the reciprocal of the number"

2*1/x = 40 * 1/50 "two times the reciprocal of the number equals 40 times the reciprocal of 50"

Find the number:

2/x=40/50

x = 2 (50) / 40

x=2.5

The number is 2.5.
