0.5 multiplied by a number The product is three decimal places, and the integral part of the product is 1. If you use the "rounding" method to get the approximate value, if you keep the integer, the product is 2; if you keep one decimal place, the product is 2.0; if you keep two decimal places, the product is 2.00. Find this number. It's better to answer before 9 o'clock tonight, please as soon as possible
When 0.5 is multiplied by a number, the last digit is 0 or 5, because the product retains two decimal places, the decimal is 2.00, that is, the end is 5
The other two decimal places are 0.99
995
1.995/0.5=3.99
A fraction is multiplied by 23 and 47 respectively. The sum of the two products is 1314. The fraction is______ ．
Let this number be X. from the meaning of the question, we can get: 23x + 47x = 1314, & nbsp; & nbsp; 2621x = 1314, & nbsp; & nbsp; & nbsp; & nbsp; X = 34. A: the score is 34. So the answer is: 34
