Given the ratio of maple trees to pine trees is 7:5, we can use this ratio to find the number of maple trees when there are 60 pine trees.
Let's set up the ratio:
- Let the number of maple trees be \( 7x \) (based on the "7" in the ratio).
- Let the number of pine trees be \( 5x \) (based on the "5" in the ratio).
According to the problem, you have 60 pine trees, which means:
\[ 5x = 60 \]
Now, solve for \( x \):
\[ x = \frac{60}{5} = 12 \]
Now, we can find the number of maple trees:
\[ \text{Number of maple trees} = 7x = 7 \times 12 = 84 \]
So, there should be approximately 84 maple trees in that area.
