Sofia and her grandparents set up chairs and tables for her quinceanera, an important even celebrating her 15th birthday. The ratio of chairs to tables is 6: 1. What is the total number of chairs they need for 18 tables?

To find the total number of chairs needed, we use the ratio of chairs to tables, which is 6:1. This means there are 6 chairs for every 1 table.

Given that there are 18 tables, you can calculate the number of chairs by multiplying 18 by 6:

\[
\text{Number of chairs} = 6 \times 18 = 108
\]

So, Sofia and her grandparents need 108 chairs for 18 tables.

2. How many tables would they need if they had 90 chairs and kept the same 6:1 ratio?
3. If they wanted to set up 12 tables, how many chairs would be required?
4. What would be the total number of chairs needed for 24 tables?
5. If they accidentally set up 120 chairs, how many tables do they need to match the 6:1 ratio?

**Tip:** Ratios are a helpful way to understand the relationship between two quantities. Always multiply or divide both parts of the ratio by the same number to maintain the relationship.

Learn how to calculate the total number of chairs needed for Sofia's quinceanera celebration using a ratio of chairs to tables (6:1). Understand the relationship between chairs and tables and apply multiplication to find the solution for 18 tables.
