Answer
Ebony had 25 pounds remaining.
Work Step by Step
Ebony had $100 \times \frac{3}{4}$ pounds of rice after selling $\frac{1}{4}$ of the rice to her neighbor. Multiply by $\frac{1}{3}$ to determine how much Ebony had after giving $\frac{2}{3}$ to her parents.
$100 \times \frac{3}{4} \times \frac{1}{3}$
Estimate
$100 \times 1 \times 0 = 0$
Solve
$100 \times \frac{3}{4} \times \frac{1}{3}$
Reduce by common factors of 3 and 4
$25 \times \frac{1}{1} \times \frac{1}{1}$ = 25 pounds
