The sum of a and B is 303.49. If the decimal point of B moves one place to the left, it is equal to A. what are the two numbers? The answer is yes, but how to explain it to the child? The son asked why he divided it by 11, but he couldn't explain it. Who can explain it? Grade 4 of primary school

Let a be X,
If the decimal point of number B is moved one place to the left, it is equal to number a
So B is 10x
The sum of a and B is 303.49
That is x + 10x = 303.49
11x=303.49
x=303.49/11
x=27.59
59 and 275. 9 respectively
