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!
