3/8:1/4

To divide the fractions \( \frac{3}{8} \) by \( \frac{1}{4} \), you can multiply by the reciprocal of the second fraction: \[ \frac{3}{8} \div \frac{1}{4} = \frac{3}{8} \times \frac{4}{1} \] Now, multiply the numerators and the denominators: \[ = \frac{3 \times 4}{8 \times 1} = \frac{12}{8} \] Next, simplify \( \frac{12}{8} \): \[ \frac{12}{8} = \frac{3}{2} \] So, \( \frac{3}{8} : \frac{1}{4} = \frac{3}{2} \) or \( 1.5 \).
