Question

Marissa rode her bike to the park and back home. She lives 2 and 3/10 miles from the park. How many miles did Marissa ride her bike in all?

Answer 1

2$\frac{3}{10}$ * 2
this can be shortened to :
$\frac{23}{10}* \frac{2}{1}= \frac{23*2}{10} = \frac{46}{10}=4 \frac{6}{10} = 4 \frac{3}{5}$
