The sum of a and B is 42.14. If the decimal point of a moves one place to the left, it is exactly equal to 35 of B, then a is a______ .

Let the number a be x, then the number B is 42.14-x. according to the meaning of the question, we can get the equation: X △ 10 = 35 (42.14-x), & nbsp; & nbsp; & nbsp; X = 6 (42.14-x), & nbsp; & nbsp; & nbsp; X = 252.84-6x, & nbsp; & nbsp; 7x = 252.84, & nbsp; & nbsp; & nbsp; X = 36.12, answer: the number a is 36.12. So the answer is: 36.12
