So pretty straight forward
So first you divide the amount of cheese by 3
so for the first one you have 18 pounds of cheese
Now 18/3=6
Now using that quotient (6) you multiply that by 8
6*8=48
So 18 pounds of cheese is 48 pizzas
Same thing with the others, even with the decimal one

which is equivalent to 1(3/8) miles
9x4=? Because there are 4 groups of 9 so it is multiplication.<span />
Answer: 1. 200, 2. 300
Step-by-step explanation:
40 * 10/2 = 400/2 = 200
or this way:
40 = 20%
40/2 = 20
20 = 10%
20 * 10 = 200
——————————————
90 * 10/3 = 900/3 = 300
or this way:
90 = 30%
90/3 = 30
30 = 10%
30 * 10 = 300
