Maryam had to sail 4 2⁄3 miles to reach her destination. at the end of the day, she had sailed 3 1⁄3 miles. how far was she from her destination?

Ok so
A to B=4 and 2/3

she sailed 3 and 1/3
how far was she from destination (how far more does she have to travel)

3 and 1/3+how much farther=4 and 2/3
subtract 3 and 1/3 from both sides
how much farther=4 and 2/3-3 and 1/3
4 and 2/3=4+2/3
-3 and 1/3=-3-1/3 so
how much farther=4 +2/3-3-1/3=
4-3+2/3-1/3=
1+1/3

answer is 1 and 1/3 miles more
