Answer:
89 lbs.
Explanation:
Well, if you have 4 apple trees which each have 10 pounds of apples, you need to multiply 4 x 10 to get 40 lbs of apples altogether. (lbs = pounds)
Then, you multiply the 5 peach trees by the 5 pounds of peaches, which is 25 lbs of peaches altogether.
Next, you said there are 2 pear trees with 12 pounds of pears. You need to multiply 2 x 12 to get 24 lbs of pears.
Now here's the easy part. Just add 40 lbs of apples + 25 lbs of peaches + 24 lbs of pears.
You should now have 89 lbs of fruit in all.
I hope this answered your question. :)
