Each student gets 1/8 of the cake.
we multiply 1/8 and 3/4. To do that we multiply the numerators together and the denominators together. This gives (1*3)/(8*4) =3/32 of the cake
Changed both of them to a fraction
2200 + 21.25X = 1840 +32.50X
subtract 1840 from each side
360+ 21.25X= 32.50X
subtract 21.25x from each side
360=11.25X
x= 360/11.25 = 32 minutes pool will have the same amount
21.25*32 = 680+2200 = 2880 liters
32.5*32 = 1040 + 1840=2880 liters
it will take 32 minutes and they will have 2880 liters each
