To find the fraction equivalent of 0.454545.......

It can be seen that this is a repeating decimal because 45 are repeating

One way to find the fraction equivalent is to follow the steps below

Step 1: Equate the reaction to an unknown number

let y = 0.45454545.... Equation 1

Step 2: Since there are two numbers (4 and 5) repeating, multiply the equation by

100.

If there is just one repeating decimal number, you will multiply by 10

So in simple terms, the number of repeating numbers will determine the number of zeros

So multiplying equation 1 by 100

100y = 45.45454545.... ---- Equation 2

we can now subtract equation 1 from equation 2

100y - y = 45.4545 - 0.4545

99y = 45

If 99y = 45

we can divide both sides by 99

y = 45/99

The equivalent fraction is y = 45/99
