In a 100-acre tract, the streets require 1/8 of the total land. How many acres are allocated to streets?

• A. 12.5
• B. 10
• C. 15
• D. 20

Answer: (A)

The main idea is finding a fraction of a total area. Streets take one eighth of the land, so apply that fraction to the 100-acre tract: 100 × 1/8 = 12.5 acres. You can also see it by dividing 100 by 8, which gives 12.5. Hence, 12.5 acres are allocated to streets. The other numbers would result from different fractions (like one tenth or one fifth) and do not match the one-eighth requirement.
