Answer:
20
Step-by-step explanation:
Take note of the important information/key words:
60 total ornaments
3 grandchildren
<em>Divide</em> them evenly
Set up an equation:
60 ornaments ÷ 3 grandchildren = ornaments per grandchild
60 ÷ 3 = 20 ornaments per grandchild.
In other words, each grandchild will receive 20 ornaments.
