Convert Mixed Number: Finding the Decimal Form of 2 7/100

The denominator 100 tells you the place value! Since 100 = 10², the fraction goes to the hundredths place (two decimal places). Think of it as 7 hundredths, which is 0.07.

With denominator 10, you only need one decimal place! So $\frac{7}{10} = 0.7$ and $2\frac{7}{10} = 2.7$.

Yes! A mixed number means addition: $2\frac{7}{100} = 2 + \frac{7}{100} = 2 + 0.07 = 2.07$. The whole number and fraction are combined.

Count the zeros! Denominator 10 (1 zero) = tenths (1 decimal place). Denominator 100 (2 zeros) = hundredths (2 decimal places). Denominator 1000 (3 zeros) = thousandths (3 decimal places).

You'll need to convert it first! For example, $\frac{1}{4} = \frac{25}{100} = 0.25$. Find an equivalent fraction with a power of 10 in the denominator, then convert to decimal.
