Factors of 40 : 1X40 , 2X20 , 4X10 , 5X8
Factors of 90 : 1X90 , 2X45 , 3X30 , 5X18
Common factors : 1,2,5
40% of $90= 40% * 90= 0.4 * 90= $36
-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.
40 + 90 = 130
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
Factors of 90 will be factors of 180.
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. :)
Least common multiple of 40 and 90 is 360.
