To find the original number, we first need to find what the total number is when 25% is 45.
Let the original number be x.
25% of x is 0.25x. We are given that 0.25x = 45.
So, x = 45 / 0.25 = 180.
Now, we need to find what 45% of 180 is.
45% of 180 is 0.45 * 180 = 81.
Therefore, 45% of the number is 81.
If 25% of a number is 45 and 70% of the same number is 126, find 45% of that number.
