So what you have to do is make the denominators equal. You do that by finding out what number they can both go into which is 60. 12 can go into 60 5 times and so you have to do 9/12 times 5 which is 40/60. then 5 goes into 60 12 times so you have to do 1/5 times 5 which is 12/60. Then you see that 40/60 >12/60 therefore the class ate more of the pepperoni pizza
V=LWH
if legnth AND width AND height are dobuled
V=2L2W2H
V=2*2*2LWH
V=8LWH
weight increases by 8 times
0.3 time s8=2.4
answer is 2.4lb
uhm i think its 15 cause you just add them all i guess
