1. Using Proportions with Percent

2. Write down this Proportion!
percent = Part
100 Whole
The number after the word “of” is the denominator (bottom number).

3. Using Proportion to find Percent
Ex. 5 is what percent of 25?
n = (part)
(whole)
Solve for n.
Round to the tenths place
You Try: What percent of 60 is 15? (set up & solve)

4. Here is the Proportion again!
percent = Part
Whole

5. Using proportion to find Part
Remember: percent always goes over 100! The number after the word “of” is the denominator. Ex. What is 75% of 95? 75 = n You Try: 49% of 128 is what number? – round to tenths place.

6. Here is the Proportion again!
percent = Part
100 Whole

7. Using Proportion to find Whole
HINT: The number after the word “of” is the denominator. Ex. 30% of what number is 5 30 = n You Try: 86 is 65% of what number? (round to tenths place)

8. Here is the Proportion again!
percent = Part
Whole
