Multiply the total weight by the percentage
16 ounces x 0.03 = 0.48
0.48 ounces is fat
Jim is correct because the ratios need to compare with the total amount of people surveyed. 55, 80, and 65 are numbers that don't fit in and don't tell the overall ratio. You can tell this by writing it as a fraction.
Ex: 35:100 = 35/100. This literally means 35 out of 100 people exercise in the morning.
Hope this helps! If you have any questions, just ask!
-16t^2+400=0
16t^2=400
take square root on both sides.

4t=20
t=20/4
t=5
Well there are 12 players and 9 are in 8th grade so the rest is leaving 3 so 3/12 so converted to percentage is 25% hoped this helped
