Answer
a) $\frac{4}{3}$
b) $3\frac{3}{4}$
c) $1\frac{1}{2}$
Work Step by Step
To convert a mixed number to an improper fraction, multiply the denominator by the whole number portion, then add the product to the numerator.
$1\frac{1}{3}=\frac{(3\times1)+1}{3}=\frac{4}{3}$
To convert an improper fraction to a whole number, divide the numerator by the denominator. The quotient becomes the whole number portion of the mixed number. The remainder becomes the numerator of the fractional portion.
$15\div4=3,\ R:3$
$\frac{15}{4}=3\frac{3}{4}$
$3\div2=1,\ R:1$
$\frac{3}{2}=1\frac{1}{2}$
