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
The answer is 72
b/c 80% is equal to .80
so you do 90x.80

Step-by-step explanation:
Answer:
x = 45/17
Step-by-step explanation:
We can move all x to 1 side and all the numbers to another. You can add 8.7 on both sides and get that 2.3x = 0.8x + 4.5. Next, we subtract by 0.8x on both sides to get that 1.7x = 4.5, where we can then divide by 17/10 on both sides to get that x is equal to 45/10 * 10/17, so that means that x = 45/17.
