3.54repeating repeating decimal

Enter Repeating Decimal


This is a repeating decimal which can be written as 3.54, and there is a special formula to determine the fraction
The repeated piece 54 has a length of 2
Therefore, we setup two equations.
Equation 1: x = 3.54
Equation 2: 100x = 102 100x 3.54 → 100x = 100 x 3.54 → 100x = 354
Therefore, we have 100x - x = 354 - 3.54
99x = 354

Divide each side of the equation by 99


x  =  354
