1. Selena has to walk <em>to</em> school and <em>from </em>school.
That means that each day, she walks the distance from her house to the school twice.
If she walks 2/3 in a day, the distance must be half of that, or 1/3.
2. 3 batches = 3/4 cup.
Divide each side by 3.
1 batch = 1/4 cup.
3. 5 eighths minus 1 eighth = 4 eighths.
Since we have the same bottom number, we don't need to do anything special. This problem is just the same as something like <em>5 apples - 1 apple.</em>
4. First, let's convert 6 into thirds.
6 × 3 = 18
Therefore, 6 = 18/3.
Add 6 and 2/3.
18/3 + 2/3
20/3
5. To be a composite number, a number needs to be divisible by something besides 1 or itself.
Check your divisibility rules...
39 is divisible by 3 (39 ÷ 3 = 13), so this could be his house number.
6. 12 cupcakes - 9 chocolate = 3 vanilla.
3 vanilla cupcakes out of 12. (3/12)
We can simplify this fraction. 3 and 12 are both divisible by 3.
3/12 = 3÷3 / 12÷3 = 1/4
