Answer 1

To find the total number of trees, you can simply add the number of oak trees to the number of maple trees.

1. Start with the number of oak trees: 197
2. Add the number of maple trees: 76

To make the addition easier, you can break it down:

• First, add 197 + 76:
  • You can round 76 to 80 (to simplify the calculations initially).
  • 197 + 80 = 277 (which is an approximation).
  • Since you added 4 extra (80 - 76 = 4), you subtract 4: 277 - 4 = 273.

So, the total number of trees is 273.
