During the winter vacation, my parents and I went to the Tiger Run. When I walked into the teahouse, a plum blossom fragrance came to my nose. It turned out that nine plum trees were planted in the small courtyard of the teahouse. I also found that there are many pine trees around the teahouse, which are vigorous and powerful against the white snow. I counted carefully, and there were 36 trees. Suddenly, two little squirrels ran out of a nearby pine tree, so we fed them peanuts. Soon, the smell of peanuts attracted two little squirrels, who scrambled to eat peanuts. We laughed it off. That is really a happy "mouse"!

1. How many plum trees and pine trees are there?

9+36=45 (tree)

A: A * * * has 45 trees.

2. How many times is the pine tree bigger than the plum tree?

36÷9=4 (times)

Pine trees are four times as big as plum trees.

3. How many times are pine trees as squirrels?

36÷4=9 (times)

Pine trees are nine times as big as squirrels.
