Answer 1

To use friendly percents to find 35% of 80, you can break it down into simpler steps using easier percentages to work with. Here's how you can do it:

1. **Break Down 35%**: First, recognize that 35% can be broken down into two parts: 30% and 5%. This makes it easier to calculate.

2. **Calculate 30% of 80**:
- To find 30% of 80, you can multiply 80 by 0.30:
\[
30\% \text{ of } 80 = 80 \times 0.30 = 24
\]

3. **Calculate 5% of 80**:
- Next, find 5% of 80 by multiplying 80 by 0.05:
\[
5\% \text{ of } 80 = 80 \times 0.05 = 4
\]

4. **Add the Two Results**: Add the results of 30% and 5% together:
\[
30\% \text{ of } 80 + 5\% \text{ of } 80 = 24 + 4 = 28
\]

Therefore, 35% of 80 is 28. This method of breaking down percentages into "friendly" or simpler numbers helps make calculations more manageable!
