The factors of 45 are:
1, 3, 5, 9, 15, 45
The factors of 80 are:
1, 2, 4, 5, 8, 10, 16, 20, 40, 80
The common factors are:
1, 5
45 percent of 80 = 36
The number which goes into both 94 and 45 is 1.
200% of a number is 90, so 100% of a nubmer is 45, so 45 is 80% 0f a number therfore a number is 45/80*100=225/4
5 goes into 45 and 55
the number 15.
45 + 35 = 80
45 percent of 80 = 36
If 45 = 120% then simply divide 45 by 120, to find 1%, which is 0.375 and then multiply this by 80 to find 80%, which is 30 - or - 1.20X = 45; X = 45/1.20 = 37.5; then 80% of the number is: 37.5 X .80 = 30
Well, darling, 80% of 45 is 36. You just move that decimal point one place to the left to find 10%, then multiply by 8 to get your answer. So, there you have it, 36 is 80% of 45. Math can be a breeze when you know the tricks!
36/0.8 = 45. Therefore, the number that 36 is 80 percent of, is 45.
The number which goes into both 94 and 45 is 1.

As you might have already figured out, you have to count every 2nd number! For example, it goes a little something like this: 10 45 80 and 125, and the second number line is 30 40 50 and 60. So that means, in the next 8 numbers, the pattern goes like this: 10 30 45 40 80 50 125 60 160 70 205 80 260 90 315 and 100!
5 goes into 45 and 55
36
5 is one number that goes into 45 and 900. 45 ÷ 5 = 9 900 ÷ 5 = 180
