If a mayor is elected with 89% of the votes cast and 33% of a town's 43,000 voters cast a vote, how many votes did the mayor receive?
| 9,933 | |
| 9,649 | |
| 12,062 | |
| 12,629 |
If 33% of the town's 43,000 voters cast ballots the number of votes cast is:
(\( \frac{33}{100} \)) x 43,000 = \( \frac{1,419,000}{100} \) = 14,190
The mayor got 89% of the votes cast which is:
(\( \frac{89}{100} \)) x 14,190 = \( \frac{1,262,910}{100} \) = 12,629 votes.

A sports card collection contains football, baseball, and basketball cards. If the ratio of football to baseball cards is 5 to 2 and the ratio of baseball to basketball cards is 5 to 1, what is the ratio of football to basketball cards?
| 1:1 | |
| 25:2 | |
| 9:6 | |
| 9:1 |
The ratio of football cards to baseball cards is 5:2 and the ratio of baseball cards to basketball cards is 5:1. To solve this problem, we need the baseball card side of each ratio to be equal so we need to rewrite the ratios in terms of a common number of baseball cards. (Think of this like finding the common denominator when adding fractions.) The ratio of football to baseball cards can also be written as 25:10 and the ratio of baseball cards to basketball cards as 10:2. So, the ratio of football cards to basketball cards is football:baseball, baseball:basketball or 25:10, 10:2 which reduces to 25:2.
