#### Work Step by Step

Improper fractions can be written as whole or mixed numbers by dividing the denominator into the numerator. The quotient becomes the whole number and the remainder becomes the numerator of the fractional part, retaining the original denominator.
$\frac{5}{3}$ can be written as $1 \frac{2}{3}$ because $5 \div 3 = 1 R 2$
$\frac{7}{8}$ cannot be written as a whole or mixed number because it is not an improper fraction.
$\frac{7}{7}$ can be written as 1 because $7 \div 7 = 1$
$\frac{11}{6}$ can be written as $1 \frac{5}{6}$ because $11 \div 6 = 1 R5$
$\frac{4}{5}$ cannot be written as a whole or mixed number because it is not an improper fraction.
$\frac{15}{16}$ cannot be written as a whole or mixed number because it is not an improper fraction.
