  • Decimal: \displaystyle 1.125
  • Percent: 112.5%

1 whole + 1 of 8 equal parts

Step-by-step solution

The problem

\frac{3}{8} \div \frac{1}{3}
  1. Flip \displaystyle \frac{1}{3} and multiply. Dividing by a fraction is the same as multiplying by its reciprocal (the fraction turned upside down).

    \frac{1}{3} \;\rightarrow\; \frac{3}{1}
    = \textcolor{#0b5c56}{\frac{3}{8}} \times \textcolor{#0b5c56}{3}
  2. Multiply. A whole number is itself over 1. Top times top, bottom times bottom.

    = \frac{3 \times 3}{8 \times 1} = \textcolor{#0b5c56}{\frac{9}{8}}
  3. Check that it can't be simplified. 9 and 8 have no common factor other than 1, so this is the simplest form.

    \text{GCF}(9, 8) = 1
  4. Write it as a mixed number. Divide: 8 goes into 9 1 time with 1 left over. The whole number is 1, the remainder 1 becomes the numerator, and the denominator stays 8.

    9 \div 8 = 1\ \text{R}\ 1
    = \textcolor{#0b5c56}{1\frac{1}{8}}
