How can 85% be broken down with friendly percents to find 85% of a number?

Question

2(25%) + 3(10%)
3(25%) + 10%
5(10%) + 25%
4(10%) + 2(25%)

Answer 1

To break down 85% of a number using friendly percents, we can look for combinations that make the calculation easier.

Let’s examine the options:

1. 2(25%) + 3(10%)

   • This equals: \( 50% + 30% = 80% \) (not 85%)

2. 3(25%) + 10%

   • This equals: \( 75% + 10% = 85% \) (this works!)

3. 5(10%) + 25%

   • This equals: \( 50% + 25% = 75% \) (not 85%)

4. 4(10%) + 2(25%)

   • This equals: \( 40% + 50% = 90% \) (not 85%)

The correct breakdown using friendly percents to represent 85% of a number is 3(25%) + 10%.
