Answer:
37.5 percent
Step-by-step explanation:
Well, there are 25+15=40 total people. Since there are 15 children, the percent is 15/40, which is equal to .375

Mean is equal to the sum of terms divided by the number of terms.


Answer:
40x30= 1200, 20x15=300, 300/1200= 1/4.
Step-by-step explanation:
You can also visualize it. Imagine a field 40’ long and the boy cut the top 20’ of it but left 20’ of the bottom, he would have cut half of it at this point. Now it’s 30’ wide and he cut the left 15’ of what’s remaining but left the right 15’ uncut. So now there’s a 20’x15’ bottom right corner left uncut. There are 4 sections that are 20’x15’ and he left one out of four uncut, otherwise written as 1/4.
So since the shipping box is 3 / 3 1/4 you can fit 6 1/4 ÷ 2/4
