Using the rounding method, the accuracy is 0.01, and the approximate value of 5.649 is 0.01______ ．
The result from 5.649 to 0.01 is 5.65, so the answer is 5.65
What is the approximate value of 5.649 rounded to 0.1?
649 the approximate value rounded to 0.1 is 5.6
There is a formula: A / 3 + B / 5 + C / 7 ≈ 1.16, the letters a, B and C on the left are all natural numbers, and the answer on the right is to write the approximate value after rounding, and find a, B and C
Because the final answer is about 1.16
So a / 3
