It’s simple enough.
To find the percentage of the students who said the amount of homework was just right…
…we add the numbers of boys plus the number of girls who thought it was just right…
…and divide that by the total number of students... then multiply by 100, to turn it into a percentage.
Looking at our poll results, there were 4 boys and 2 girls who answered “just right.”
The total number of students can be found by adding 18, 17, 3, 4, 4, and 2. Which comes to 48.
6 over 48 is 1/8…or .125.
Multiply that by 100, and we get our percentage which is 12.5%
And THAT answer… is juuuust right.
