Multiply a number by 10, the number is 36 more than the original number, the original number is []

A number multiplied by 10 gets 36 times more than the original number, and a number multiplied by 10 gets 9 times more than the original number, that is, 36 is 9 times the number. According to the meaning of division, this number is 36 △ 9 = 4
36÷（10-1）
=36÷9,
=4．
A: the original number is 4

2. Some problems about arithmetic of significant number Is the operation process of 8.0421 / (6.038-6.034) + 30.9 like this?: 6.038-6.034 = 0.004 8.0421/0.004 = 2205.25 (since the least significant digit is one, the result should also retain one significant digit, so the original formula is about 2 * 10 ^ 3? So it can be added to 30.9. According to the highest suspicious digit, is the result still 2 * 10 ^ 3? There is another problem, Is the approximate number of 2205.25 taken first and then added by 30.9, or is the approximate number of 2205.25 and 30.9 taken first and then added by 30.9?
