40% of $90= 40% * 90= 0.4 * 90= $36
-40 - 90 = -130
40 + 90 = 130
The GCF of 40, 45, and 90 is 5 The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40 The factors of 45 are 1, 3, 5, 9, 15, and 45 The factors of 90 are 1, 2, 3, 5, 6, 10, 15, 18, 30, 45, and 90 So the greatest common factor is 5.
Two of the factors of 40 are odd. The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
40
90*40= 3600
40% = 0.4 Therefore, 40% off $90= $90 - (0.4 x $90) = $54
To find 90% of 40, just multiply .90 times 40, which equals 36. Since 10% of 40 is 4, then 90% of 40 are 4*9=36.
40% of 90 is 36! hope it helps. :)
