actually sice 40 is even and 45 is not the correct answer would be 43.5
42.5
85-40 = 45 and 45+45 = 90
18 is 45% of 40
45 of 40 = 45*40 = 180045 of 40 = 45*40 = 180045 of 40 = 45*40 = 180045 of 40 = 45*40 = 1800
45
6.5
31
31.
42.5
If you are adding one to the number you subtract each time, then 31 would be the next number. 46 - 1 = 45 45 - 2 = 43 43 - 3 = 40 40 - 4 = 36 36 - 5 = 31, etc...
18 is 40% of 45.
85-40 = 45 and 45+45 = 90
Since 40 + 5 = 45 and 50 - 5 = 45, 45 is exactly between 40 and 50. It is not closest to either number.
45
18 is 45% of 40
It is: 40
