Assuming the can is a cylinder set up the equation V=pi(r)^2h
215=pi(r)^2(7.5)
r^2=9.1248
r=3.021
<span> all we need to do is make the sum of the numerators be the new numerator, and the sum of the denominators be the new denominator. So, for example, a </span>fraction between<span> 7/13 and 6/11 is (7 + 6)/(13+ 11) =13/24</span>
