Answer:

Step-by-step explanation:

1/45 + 1/x = 1/25

The common denominator is

45: 5 * 3 * 3

25:5 * 5

x: x

You need two 3s and two fives

9 * 25 * x= 225x

Multiply the equation by 225x

225x ( 1/45 + 1/x = 1/25)

25 x + 225 = 45x Subtract 25x from both sides

225 = 45x - 25x

225 = 20x Divide by 20

x = 225/20

x = 11.25
