First of all, this shouldn't be in high school category.
Second, 20 divided by 2 is 10. Dividing is like subtraction. You would subtract 20 by 2, and you would find that after 10 times, you will get to zero.
The coordinates are (-3/4, 1/2)
this is also equivalent to (-0.75, 0.5) if that helps understand if further!
22%=0.22 as a decimal, and 0.22 is written as 11/50
To find out the number of hours per week, we have to divide 24 by 4.
24 ÷ 4 = 6
Monique volunteered 6 hours per week at the animal shelter.
Hope this helps!
