Problem:
Carmen's dad grilled 30 burgers for her volleyball team's picnic. He put cheese on
2/5 of the burgers to make cheeseburgers. How many cheeseburgers did Carmen's dad make?
---
Step 1: Understand the fraction
We are told that
2/5 of the 30 burgers had cheese. So we need to find:
> What is
2/5 of 30?
This means we need to multiply:
$$
\frac{2}{5} \times 30
$$
---
Step 2: Multiply the fraction by the whole number
We can rewrite 30 as a fraction:
$$
\frac{2}{5} \times \frac{30}{1} = \frac{2 \times 30}{5 \times 1} = \frac{60}{5}
$$
Now divide:
$$
\frac{60}{5} = 12
$$

You could also think of it in steps:
- 1/5 of 30 = 6 (since 30 ÷ 5 = 6)
- So 2/5 = 2 × 6 =
12
