Fabulous Fruit

Solution

Mr. Madison picked 80 pieces of fruit on Thursday.

Explanation

Step 1

Find out how many trees of each kind he had.

14 fruit trees in all
1 apricot tree
− 1 pear tree
equals
12 trees left, including apple, peach, and plum

The apple, peach and plum trees are evenly divided, so:
12 ÷ 3 = 4
There are 4 apple trees.
There are 4 peach trees.
There are 4 plum trees.

Step 2

Use the clues to figure out how many pieces of fruit he picked from each tree.

Kind of tree Number of trees How many pieces of fruit he picked from each tree Number sentence to show how many pieces of fruit he picked How many in all
Apricot 1 0    
Pear 1 4    
Apple 4 6    
Peach 4 3    
Plum 4 10    
Total 14      

Step 3

Write a number sentence to show how many pieces of fruit he picked.

Multiply.

Kind of tree Number of trees How many pieces of fruit he picked from each tree Number sentence to show how many pieces of fruit he picked How many in all
Apricot 1 0 1 tree x 0 apricot = 0 0
Pear 1 4 1 tree x 4 pears = 4 pears 4
Apple 4 6 4 trees x 6 apples = 24 apples 24
Peach 4 3 4 trees x 3 peaches = 12 peaches 12
Plum 4 10 4 trees x 10 plums = 40 plums 40
Total 14     80

Step 4

Add the number of fruit of each kind to see how many pieces of fruit he picked in all.

This is another way to set up the chart.

  Apricot Pear Apple Peach Plum Total
How many trees 1 1 4 4 4 does not matter
How many fruits 0 4 6 3 10 does not matter
Multiply: trees x fruit
  1
x 0
equals
  0
  1
x 4
equals
  4
  4
x 6
equals
  24
  4
x 3
equals
  12
   4
x 10
equals
  40
does not matter
Total of each kind of fruit 0 4 24 12 40 80
