The sum of a and B is 27.5. If you move the decimal point of B one place to the right, it will be the same as a. what is a twenty-five B = 27.5 / 11 = 2.5 A = 10 * 2.5 = 25 twenty-seven

The sum of a and B is 27.5. If you move the decimal point of B one place to the right, it will be the same as a. what is a twenty-five B = 27.5 / 11 = 2.5 A = 10 * 2.5 = 25 twenty-seven

First of all, we should understand that to move the decimal point of B to the right is to expand B by 10 times!
Let a be x and B be y
x=10y
x+y=27.5
The solution is x = 275 / 11, y = 55 / 22
