The area of the room must equal the sum of the areas of the tiles...
20*30=n(2*3)
600=6n
n=100
So 100 tiles are needed.
12 / 4 = 3. That means that 3 lots of 4 go into 12. If the 2 fractions are equivalent, then the numerator (the top number) for 3/4 times by 3 should equal the numerator for 11/12. However, 3 X 3 = 9. 9/12 is not the same as 11/12.

Jeff bought 1.5 pounds of pork.
1 pound of pork = 3.64
0.5 pounds of pork = 1.82 (divided 3.64 by 2 to find 0.5 pounds of pork)
3.64 + 1.82 = 5.46
Jeff also bought 2.5 pounds each of beer and chicken.
1 pound of beef = 5.99
2 pounds of beef = 11.98
0.5 pounds of beef = 2.995 (5.99 divided by 2)
11.98 + 2.995 = 14.975
1 pound of chicken = 4.79
2 pounds of chicken = 9.58
0.5 pounds of chicken = 2.395
9.58 + 2.395 = 11.975
Add up the total amount of the 1.5 pounds of pork and 2.5 pounds each of beef and chicken.
5.46 + 14.975 + 11.975 = $32.41
