It’s simple enough.

00:31

To find the percentage of the students who said the amount of homework was just right…

00:36

…we add the numbers of boys plus the number of girls who thought it was just right…

00:40

…and divide that by the total number of students... then multiply by 100, to turn it into a percentage.

00:46

Looking at our poll results, there were 4 boys and 2 girls who answered “just right.”

00:52

The total number of students can be found by adding 18, 17, 3, 4, 4, and 2. Which comes to 48.

01:04

6 over 48 is 1/8…or .125.

01:11

Multiply that by 100, and we get our percentage which is 12.5%

01:16

And THAT answer… is juuuust right.
