Final answer:
Abdul must walk 1/3 mile farther to reach the market, calculated by subtracting the distance he has already walked (4/9 miles) from the total trip distance (7/9 miles).
Step-by-step explanation:
Abdul has walked 4/9 miles of his trip to the market, which is a total distance of 7/9 miles. To find out how much farther he must walk, we need to subtract the distance he has already walked from the total distance of the trip. Here is the step-by-step calculation:
- Subtract the distance walked from the total distance: 7/9 miles - 4/9 miles.
- Simplify the subtraction by subtracting the numerators and keeping the denominator the same, since both fractions have the same denominator.
- The result is 3/9 miles, which can be simplified by dividing both numerator and denominator by 3.
- The simplified distance Abdul has yet to walk is 1/3 mile.
Therefore, Abdul must walk 1/3 mile farther to reach the market.
