Catherine walks her dog 3/4 mile every day how far does she walk each week.

muminat

Answer:

$5\frac{1}{4}\text{ miles}$

Step-by-step explanation:

Given,

The number of miles she walks every day = $\frac{3}{4}$

∵ 1 week = 7 days,

⇒ 1 day = $\frac{1}{7}$ week,

Thus,

The number of miles she walks $\frac{1}{7}$ week= $\frac{3}{4}$

⇒ The number of miles she walks in a week = $\frac{3}{4}\times 7=\frac{21}{4}=5\frac{1}{4}$
