20' x 21' x 36" = 47 cubic yards, but 20' x 21' x 4" is only 15.67 cubic yards.
$36 x .20 ------ $7.20
21/36 x 100 = 58.3 recurring (that is, 58.3333..) percent.
x + 21 = 36Subtract 21 from each side:x = 15
7/12 x 36/1 = 252/12 = 21 or 21/1

36 x 20?
you can write an equation: x-20=36 and move 20 to the 36 side and you do so by adding 20, so basically 20+36=56, x =5
21/36 x 100 = 58.3 recurring (that is, 58.3333..) percent.
x + 21 = 36Subtract 21 from each side:x = 15
16 + x = 36x = 36 - 16 = 2016 + 20 = 36
7/12 x 36/1 = 252/12 = 21 or 21/1
Call the numbers a & b, a being the larger. (a - b) x 100/a will give the difference as a percentage of a. EG: What is the percentage difference between 36 and 20? a = 36, b = 20; then (36 - 20) x 100/36 ie 1600/36 = 44.4recurring% To find the difference as a percentage of the lower number just swop a & b and ignore minuses. as above but a = 20 & b = 36: (20 - 36) x 100/20 = 16 x 100/20 = 1600/20 = 80%
21 x 20 = 420
36 - 21 + 15 = 30 36 - 21 - 15 = 0
What % of 20 is 36? It is the same as 36/20, or 18/10, or 180/100. So, 180% of 20 is 36. The correct answer is 180.
