It is 288.
93 x 90 x 90 x 80= 8370 x 90 x 80= 753,300 x 80= 60,264,000The answer is 60,264,000.
If you have 25 + __ = 90, the first step is to rearrange this problem into something you can answer. This would make the new problem 90 - 25 = ____. Once you solve this (It equals 65 by the way) you can then do 25 + 65 = 90. This makes it a true statement. 5 (from 25) + 5 (from 65) = 10 and 20 + 60 = 80, and finally 80 + 10 = 90.
(New - Original)/Original x 100% = Differences/Original x 100% = +% (increased) = -% (decreasing) ---- e.g. 1) (100 - 90)/90 x 100% = 10/90 x 100% = 1000/90% = +11 1/9% ---- e.g. 2) (60 - 80)/80 x 100% = -20/80 x 100% = -2000/80% = -25%
x / 5 = 80 / 25 x = 80 / 25 * 5 x = 16
90 * 80 = 7,200
Let X = gallons of 80% antifreeze Then 0.80X + .25 (90) = .70( 90 + X) .80X + 22.5 = 63 + .70X .1X = 41.5 X = 415 gallons
25% off of 80:= 25% discount applied to 80= 80 - (25% x 80)= 80 - (0.25 x 80)= 80 - 20= 60
Usually, when the word "of" appears, it means to multiply. 25 percent of 80 = 0.25 x 80 = 20 2/3 of 90 = 2/3 x 90 = 60 It works in reverse by dividing. What fraction of 90 is 60? 60/90 = 2/3 What percent of 80 is 20? 20/80 = 0.25
90 = 100% 25 = X% X = 25x100 ÷ 90 X = 27.777777777777%
90/80 x 100 = 112.5 Therefore, 90 is 112.5 percent of 80.
25% x 80 = 0.25 x 80 = 20
