Final answer:
To find how much farther Joan walks to school than Maria, subtract the distance Maria walks from the distance Joan walks. The result is 1(5)/(12) miles.
Step-by-step explanation:
To find how much farther Joan walks to school than Maria, you need to subtract the distance Maria walks from the distance Joan walks. Joan walks 2(2)/(12) miles and Maria walks 1(7)/(12) miles.
To subtract the fractions, you need to have a common denominator. In this case, the common denominator is 12.
So, the calculation becomes 2(2)/(12) - 1(7)/(12). Subtract the numerators and keep the denominator the same. The result is 1(5)/(12) miles. Therefore, Joan walks 1(5)/(12) miles farther than Maria to school.
