Math Problem Statement

100 multiply 0.106 with dots above 0 and 6(recurring decimal)

Solution

The given number is 0.060.\overline{06}, which means the decimal 0.060606060.06060606\ldots repeats indefinitely.

Step 1: Convert 0.060.\overline{06} into a Fraction

Let x=0.06x = 0.\overline{06}.
Multiplying both sides by 100 (since the repeating part has two digits):
100x=6.06100x = 6.\overline{06} Now subtract the original equation from this new equation:
100xx=6.060.06100x - x = 6.\overline{06} - 0.\overline{06} 99x=699x = 6 x=699x = \frac{6}{99} Simplify the fraction:
x=233x = \frac{2}{33}

Step 2: Multiply by 100

100×233=20033100 \times \frac{2}{33} = \frac{200}{33}

Step 3: Convert to Decimal

200336.06\frac{200}{33} \approx 6.06

So,
100×0.066.06100 \times 0.\overline{06} \approx 6.06
