Answer:
2. D [tex]\frac{1}{2}[/tex] inch per hour
3. C [tex]\frac{4}{5}[/tex] km
Eli chose A because he multiply 5[tex]\frac{3}{5}[/tex] km and 7 days; instead of dividing.
[tex]\frac{28}{5}[/tex] * 7= [tex]\frac{196}{5}[/tex] which is 39[tex]\frac{1}{5}[/tex]
Step-by-step explanation:
2. Divide the inches of rain by hours
12[tex]\frac{1}{4}[/tex] inches of rain ÷ 25[tex]\frac{1}{2}[/tex] hours; convert to proper fraction
[tex]\frac{49}{4}[/tex] ÷ [tex]\frac{51}{2}[/tex]
[tex]\frac{49}{4}[/tex] * [tex]\frac{2}{51}[/tex] = [tex]\frac{98}{204}[/tex] = [tex]\frac{49}{102}[/tex] which is approximately [tex]\frac{1}{2}[/tex] inch per hour
3. Divide km by days
5[tex]\frac{3}{5}[/tex] km / 7 days = [tex]\frac{28}{5}[/tex] ÷ 7 = [tex]\frac{28}{5}[/tex] * [tex]\frac{1}{7}[/tex] = [tex]\frac{4}{5}[/tex] km
Eli chose A because he multiply 5[tex]\frac{3}{5}[/tex] km and 7 days; instead of dividing.
[tex]\frac{28}{5}[/tex] * 7= [tex]\frac{196}{5}[/tex] which is 39[tex]\frac{1}{5}[/tex]
