Marneshia walked three over eight of a mile in three over five of an hour. What equation can be used to calculate her unit rate

Rama09 [41]

3/8 mile in 3/5 hour
$\frac{ \frac{3}{8} }{ \frac{3}{5} }$
we want to find miles per hour or m/1h
convert 3/5 to 1 by multiplying it by 5/3
keep the fraction the same by multiply ing the whole thing by
$\frac{ \frac{5}{3} }{ \frac{5}{3} }$ to get

$\frac{ \frac{15}{24} }{ \frac{15}{15} }$ =
$\frac{ \frac{5}{8} }{ 1}$ =5/8 miles per hour
