Im not sure if i am understanding the question correctly...
If you are asking if Jama's mom is correct, then no. she is wrong. this is because
if you take the proportion, (is/of)=(%/100) you get (x/30)=(70/100). You then solve for x which in this case would be 21 students are wearing tennis shoes.
Hope this helps.
It would be 18.75 because if you put it into a mixed number then multiply by 5 you get 18.75
keeping in mind that 21 months is more than a year, since there are 12 months in a year, then 21 months is really 21/12 years.


so, clearly, you can see who's greater.
