Type the missing number to complete the proportion.90 chairs at 15 tables = 6 chairs at tablesSubmit

1. Break Down the Problem

We need to find the number of tables corresponding to 6 chairs when we know that 90 chairs are used for 15 tables. We'll set up a proportion to find the missing value.

2. Relevant Concepts

The proportion can be set up as follows: $\frac{90 \text{ chairs}}{15 \text{ tables}} = \frac{6 \text{ chairs}}{x \text{ tables}}$ Where $x$ represents the number of tables corresponding to 6 chairs.

3. Analysis and Detail

To solve the proportion, we can use cross-multiplication: $90 \times x = 6 \times 15$ Calculating the right side: $6 \times 15 = 90$ Now substituting back: $90x = 90$ Next, divide both sides by 90: $x = \frac{90}{90} = 1$

4. Verify and Summarize

We have found $x = 1$. This means if there are 6 chairs, then there is 1 table according to the given proportion.

Final Answer

The missing number of tables is $\boxed{1}$.
