How to write the equation of 3 84 0 7 cyclic decimal series vertical result with only two decimal pl

Analysis of the vertical calculation process 38400 7

Problem solving idea: the dividend from the high position of each digit of the divisor to the divisor operation, each time the calculated quotient is retained, the remainder is added to the next digit for operation, in this order the dividend is calculated so the digits, the obtained quotient is combined in order, and the remainder is the result of the last operation.

Problem solving process: Step 1: 38 7=5 The remainder is: 3Step 2: 34 7=4 The remainder is: 6

Step 3: 60 7=8 The remainder is: 4

Step 4: 40 7=5 The remainder is: 5

According to the above calculation steps, the combination result is a quotient of 5485 and a remainder of 5, because the dividend is expanded by 1000 times, so the quotient is the remainder.

Check: Keep two decimal places approximately equal to.

Extended information for checking: The four rules of operation (calculated in order, multiplication and division first and then addition and subtraction, parentheses are calculated first and parentheses are calculated first, and power is calculated first and multiplied first) that is, the off-form operation (recursive equality calculation) needs to be carried out under the premise of this principle. Problem solving process:

If you have any doubts, please ask and be satisfied.

Vertical: <> divide the divisor by the high position of the dividend to see the first 2 digits of the dividend.

Column vertical:

Expand the divisor by a factor of 10 and remove the decimal point to make it an integer.

The dividend is also multiplied by a factor of 10 at the same time.

First, remove the decimal point, do not need to move it back, and then move the decimal point backward by one place.

= Leave two decimal places as:

The rule of multi-digit division:

1) Divide from the high position of the dividend, how many digits there are in the divisor, look at the first few digits of the dividend, if it is not enough to divide, look at one more place.

2) Divide to which digit of the dividend, write the quotient on which digit, if it is not enough to divide, on this digit quotient 0.

3) The remainder of each division must be smaller than the divisor, and the number of the dividend-being in this digit is dropped to the right of the remainder, and then the division continues.

Divide by column vertical calculation:

Expand the divisor by a factor of 10 and remove the decimal point to make it an integer.

The dividend is also multiplied by a factor of 10 at the same time.

Summary. The above is the specific solution idea and process, do you have any questions, you can ask <>

153 Vertical calculation cycle decimal places are kept to two decimal places.

The above is the specific solution idea and process, do you have any questions, you can ask <>

Here it is divided to exactly two decimal places. So you can bend the stool to write the result directly, if for the kind that can't be divided, and you need to keep two decimal places, you need to divide the orange to the third decimal place, and then round it according to the value of the third place! Then you can bury the envy brigade to write the result<>

The above are the specific solution ideas and processes, as well as some basic precautions, if you still have any questions, you can put forward <>

Summary. Hello, the answer to keep two decimal places in column vertical is:.

Columns are vertically retained to two decimal places.
