John can drink 2 bottles of juice in 5 minutes. To solve how long it will take him to drink 4 bottles, a proportion is set up: x/5=4/2. Cross multiplying and solving gives the answer of 10 minutes. To find what percent 32 is of 100, the problem is set up as a fraction: 32/100=x/1. Cross multiplying gives 3200=x, then dividing both sides by 1 gives the answer that 32 is 32% of 100. The document reflects on solving proportion and percent problems, finding the proportion problem easiest to solve but explaining the percent problem hardest.

• I liked solving the proportion problem
• I didn’t like explaining the percents
problem
• The hardest part was explaining my work
• The easiest part was solving the problems
