Answer
\frac{3}{8} \div \frac{1}{4} = \textcolor{#0b5c56}{\frac{3}{2} = 1\frac{1}{2}}
The quotient is 3/2 in simplest form, or 1 1/2 as a mixed number.
Decimal: \displaystyle 1.5 Percent: 150% 1 whole + 1 of 2 equal parts
Step-by-step solution The problem
\frac{3}{8} \div \frac{1}{4}
Flip \displaystyle \frac{1}{4} Dividing by a fraction is the same as multiplying by its reciprocal (the fraction turned upside down).
\frac{1}{4} \;\rightarrow\; \frac{4}{1}
= \textcolor{#0b5c56}{\frac{3}{8}} \times \textcolor{#0b5c56}{4}
Cancel common factors. Divide 4 and 8 by 4.
= \dfrac{3}{\cancel{8}_{\,\textcolor{#0b5c56}{2}}} \times \dfrac{\cancel{4}^{\,\textcolor{#0b5c56}{1}}}{1} = \textcolor{#0b5c56}{\frac{3}{2}} \times \textcolor{#0b5c56}{\frac{1}{1}}
Multiply. Top times top, bottom times bottom.
= \frac{3 \times 1}{2 \times 1} = \textcolor{#0b5c56}{\frac{3}{2}}
Write it as a mixed number. Divide: 2 goes into 3 1 time with 1 left over. The whole number is 1, the remainder 1 becomes the numerator, and the denominator stays 2.
3 \div 2 = 1\ \text{R}\ 1
= \textcolor{#0b5c56}{1\frac{1}{2}}
