Question

1/4 miles to a shoe store. Then you walk another 2/5 miles to a music store. How many miles have you walked in all?

Answer 1

Answer:

$\frac{13}{20}$

Step-by-step explanation:

$\frac{1}{4} + \frac{2}{5}$

First, we need to make the demoninators the same so we times 4 by 5 and whatever we do to the bottom, we do to the top, and 5 by 4.

$\frac{ 1 \times 5}{4 \times 5} + \frac{2 \times 4}{5 \times 4}$

$\frac{5}{20} + \frac{8}{20}$

$= \frac{13}{20}$

demoninator now doesn't change unless you're multiplying or dividing.
