musickatia [10]

Answer:

Joan Walks $\frac{7}{12}$ miles farther than maria

Explanation:

Given:

Distance walked by Nicole = 1. 11/12 miles

Distance walked by Tasha= 2. 1/12 miles

Distance walked by Maria = 1. 7 /12 miles

Distance walked by Joan = 2. 2/12 miles

To find:

How much farther Joan walks to school than Maria = ?

Solution:

We can find the distance that Joan walk more than maria by subtraction

Joan distance - maria distance

here the distance are given in mixed fraction , so lets covert them into fraction and perform subtraction

=> $2\frac{2}{12} - 1 \frac{7}{12}$

=> $\frac{24+ 2}{12} - \frac{12 +7}{12}$

=> $\frac{26}{12} - \frac{19}{12}$

=> $\frac{26 - 19}{12}$

=> $\frac{7}{12}$
