Question

India can paint 3 1/5 walls in one day. How many walls can she paint in 5 1/2 days?

Answer 1

Change the mixed numbers into fractions.

$3 \frac{1}{5}$
$3 * 5 = 15$
$15 + 1 = 16$
$3 \frac{1}{5} = \frac{16}{5}$

$5 \frac{1}{2}$
$5 * 2 = 10$
$10 + 1 = 11$
$5 \frac{1}{2} = \frac{11}{2}$

Multiply these fractions together:

$\frac{16}{5} * \frac{11}{2} = \frac{176}{10}$

Simplify the fraction.

$\frac{176}{10} / \frac{2}{2} = \frac{88}{5}$

$88 / 5 = 17 R3 = 17 \frac{3}{5}$

India can paint 17 and 3/5 walls in 5 and a half days.
