Question from Eric, a parent: how so i write a numerical or variable expression for each quantity. |
Hi Eric,
How about the number of inches in 3 feet and the number of inches in s feet?
There are 12 inches in a foot so the number of inches in 3 feet is 12 × 3 = 36.
There are 12 inches in a foot so the number of inches in s feet is 12 × s.
Sometimes we omit the multiplication symbol and say there are 12s inches in s feet.
I hope this helps,
Penny
