Max has 10 feet of ribbon. Each gift uses $r$ feet of ribbon. We need to find the expression that represents the number of gifts Max decorated.

1. Problem Description

Max has 10 feet of ribbon. Each gift uses $r$ feet of ribbon. We need to find the expression that represents the number of gifts Max decorated.

2. Solution Steps

We are given the total length of ribbon Max has (10 feet) and the length of ribbon used for each gift ($r$ feet).

To find the number of gifts decorated, we need to divide the total length of ribbon by the length of ribbon used per gift.

The formula is:

Number of gifts = $\frac{\text{Total length of ribbon}}{\text{Length of ribbon per gift}}$

Number of gifts = $\frac{10}{r}$

3. Final Answer

$\frac{10}{r}$
