Question 9 hard
Mark aimed to complete $$\frac{5}{6}$$ of his reading assignment. By evening, he had completed $$\frac{3}{4}$$ of the total book. How much of his book assignment remains to be completed?
Show answer & explanation
Correct answer: B — $$\frac{3}{12}$$
The entire book represents 1 whole. Since he completed $$\frac{3}{4}$$ of the book, the remaining part is $$1 - \frac{3}{4} = \frac{1}{4}$$. We look at the options to find an equivalent fraction: $$\frac{3}{12}$$ simplifies to $$\frac{1}{4}$$ (by dividing numerator and denominator by 3).
