Question

1. modeling real life your friend walks \\(\frac{2}{10}\\) mile to school each day. she walks the same distance home. how many miles does she walk to and from school in one 5-day school week?

Explanation:

Step1: Find daily round - trip distance

The friend walks $\frac{2}{10}$ mile to school and the same distance home. So the daily round - trip distance is the sum of the distance to school and the distance home. That is $\frac{2}{10}+\frac{2}{10}=\frac{2 + 2}{10}=\frac{4}{10}=\frac{2}{5}$ miles.

Step2: Find distance for 5 - day week

To find the total distance for a 5 - day school week, we multiply the daily round - trip distance by 5. So we calculate $\frac{2}{5}\times5$. When we multiply a fraction $\frac{a}{b}$ by an integer $n$, we have $\frac{a\times n}{b}$. Here, $a = 2$, $b = 5$, and $n = 5$. So $\frac{2\times5}{5}=2$ miles.
