Answer:

2. D $\frac{1}{2}$ inch per hour

3. C $\frac{4}{5}$ km

Eli chose A because he multiply 5 $\frac{3}{5}$ km and 7 days; instead of dividing.

$\frac{28}{5}$ * 7= $\frac{196}{5}$ which is 39 $\frac{1}{5}$

Step-by-step explanation:

2. Divide the inches of rain by hours

12 $\frac{1}{4}$ inches of rain ÷ 25 $\frac{1}{2}$ hours; convert to proper fraction

$\frac{49}{4}$ ÷ $\frac{51}{2}$

$\frac{49}{4}$ * $\frac{2}{51}$ = $\frac{98}{204}$ = $\frac{49}{102}$ which is approximately $\frac{1}{2}$ inch per hour

3. Divide km by days

5 $\frac{3}{5}$ km / 7 days = $\frac{28}{5}$ ÷ 7 = $\frac{28}{5}$ * $\frac{1}{7}$ = $\frac{4}{5}$ km

Eli chose A because he multiply 5 $\frac{3}{5}$ km and 7 days; instead of dividing.

$\frac{28}{5}$ * 7= $\frac{196}{5}$ which is 39 $\frac{1}{5}$
