Q 2 - Each day an office used seven-eighths of a box of paper. How many boxes would they have used after four days?
Answer : C
Explanation
Step 1:
Paper used in one day = $\frac{7}{8}$ box
Step 2:
Paper used in 4 days = 4 × $\frac{7}{8}$ = $\frac{4}{1}$ × $\frac{7}{8}$
= $\frac{1}{1}$ × $\frac{7}{2}$ = $\frac{7}{2}$ = 3$\frac{1}{2}$ boxes

Q 3 - A bakery uses four cups of flour to make a full size cake. If they wanted to make a cake five-eighths the size, how many cups of flour would they need?
Answer : B
Explanation
Step 1:
Flour used for 1 cake = 4 cups
Step 2:
Flour used for $\frac{5}{8}$ cake = 4 × $\frac{5}{8}$ = $\frac{4}{1}$ × $\frac{5}{8}$
= $\frac{1}{1}$ × $\frac{5}{2}$ = $\frac{5}{2}$ = 2$\frac{1}{2}$ cups

Q 4 - A farmer gives each of his cattle one-fourths of a bundle of grass every day. If he has eight cows, how many bundles of grass does he use every day?
Answer : D
Explanation
Step 1:
Grass given to one cow = $\frac{1}{4}$ bundle
Step 2:
Grass given to eight cows = 8 × $\frac{1}{4}$ = $\frac{8}{1}$ × $\frac{1}{4}$
= $\frac{2}{1}$ × $\frac{1}{1}$ = $\frac{2}{1}$ = 2 bundles

Q 5 - A chef cooked seven kilograms of rice for a party. If the guests ate two-fifths of the amount that was cooked, how much did they eat?
Answer : B
