Fraction Division Questions
1. **Problem:** If you have $\frac{3}{4}$ of a chocolate bar and you want to divide it into portions each of size $\frac{1}{2}$ of a chocolate bar, how many portions can you get?
**Solution:**
To find how many $\frac{1}{2}$ portions fit into $\frac{3}{4}$, divide:
$$\frac{3}{4} \div \frac{1}{2} = \frac{3}{4} \times \frac{2}{1} = \frac{3 \times 2}{4 \times 1} = \frac{6}{4} = \frac{3}{2} = 1 \frac{1}{2}$$
So, you can get $1 \frac{1}{2}$ portions.
2. **Problem:** A recipe requires $\frac{2}{3}$ cup of sugar, but you only have spoons that hold $\frac{1}{4}$ cup each. How many spoons of sugar do you need?
**Solution:**
Divide the total sugar by the spoon size:
$$\frac{2}{3} \div \frac{1}{4} = \frac{2}{3} \times \frac{4}{1} = \frac{8}{3} = 2 \frac{2}{3}$$
So, you need $2 \frac{2}{3}$ spoons.
3. **Problem:** You have $\frac{5}{6}$ of a yard of fabric and want to cut pieces each $\frac{1}{3}$ yard long. How many pieces can you cut?
**Solution:**
Divide:
$$\frac{5}{6} \div \frac{1}{3} = \frac{5}{6} \times \frac{3}{1} = \frac{15}{6} = \frac{5}{2} = 2 \frac{1}{2}$$
You can cut $2 \frac{1}{2}$ pieces.
4. **Problem:** A car travels $\frac{7}{8}$ of a mile in one minute. How many $\frac{1}{4}$ mile segments does the car travel in one minute?
**Solution:**
Divide:
$$\frac{7}{8} \div \frac{1}{4} = \frac{7}{8} \times \frac{4}{1} = \frac{28}{8} = \frac{7}{2} = 3 \frac{1}{2}$$
The car travels $3 \frac{1}{2}$ segments.
5. **Problem:** You have $\frac{4}{5}$ cup of paint and each small can holds $\frac{2}{5}$ cup. How many small cans can you fill?
**Solution:**
Divide:
$$\frac{4}{5} \div \frac{2}{5} = \frac{4}{5} \times \frac{5}{2} = \frac{20}{10} = 2$$
You can fill 2 small cans.
**Answer Key:**
1) $1 \frac{1}{2}$ portions
2) $2 \frac{2}{3}$ spoons
3) $2 \frac{1}{2}$ pieces
4) $3 \frac{1}{2}$ segments
5) 2 small cans
