Factors of 40 : 1X40 , 2X20 , 4X10 , 5X8
Factors of 90 : 1X90 , 2X45 , 3X30 , 5X18
Common factors : 1,2,5
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% of $90= 40% * 90= 0.4 * 90= $36
-40 - 90 = -130
Factors of 90 will be factors of 180.
40 + 90 = 130
40
90*40= 3600
Factors of 90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90.Factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.GCF (90, 80) = 10
40% = 0.4 Therefore, 40% off $90= $90 - (0.4 x $90) = $54
The greatest common factor of 75, 90, and 40 is 5. GCF = 5 Factors of 40: 1, 2, 4, 𝟱, 8, 10, 20, 40 Factors of 75: 1, 3, 𝟱, 15, 25, 75 Factors of 95: 1, 𝟱, 19, 95
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.
