Joy recorded the distances she walked each day for five days. How far did she walk in 5 days?

laila [671]

Answer: She walk $2\frac{1}{6}\ miles$ in 5 days.

Step-by-step explanation:

Since we have given that from the graph:

Distance of $\frac{1}{3}$ for 3 days.

Distance of $\frac{1}{2}$ for 1 day.

Distance of $\frac{2}{3}$ for 1 day.

So, Total distance she covered by walk in 5 days is given by

$\frac{1}{3}\times 3+\frac{1}{2}+\frac{2}{3}\\\\=1+\frac{1}{2}+\frac{2}{3}\\\\=\frac{6+3+4}{6}\\\\=\frac{13}{6}\\\\=2\frac{1}{6}\ miles$

Hence, She walk $2\frac{1}{6}\ miles$ in 5 days.

Total of miles 3/7, 2/3 and 1/2

beks73 [17]

So first make sure thtat the bottom number is the same so
7 and 3 and 2
multily them together and get 42

so multtiply 3/7 by 6/6 or 1=18/42
multiply 2/3 by 14/14=28/42
multply 1/2 by 21/21=21/42
18/42+28/42+21/42=(18+28+21)/42=67/42
simplify
1 and 25/42 miles
