1 3 2 5 1 8 17 99 By result?

If you have a few numbers, you will be classified according to the result, well, the first one is the same as the second, it belongs to a circular decimal, and the third one is inseparable.

According to the classification, one and three should be together, and the small number should be divided by the large number.

1 3,, the words of this are divided into the results of the words are a simple punishment.

I love the wardrobe divided by 1.87 divided by 99, and the word is equal to a lot of books according to the results.

You can calculate the number and then sort it according to its size.

If you want to sort the results by the results, you have to calculate the results and compare them with each other, and the answer to these three numbers is simple.

It's very simple, as long as you have a certain logic when calculating, you will be fine.

Classified by results, divided by structure, this thing should be the upper eyelid.

How? You can sort the whole number of the structure and whether the result is countable, so it's very convenient? It's great.

The result classification here is by the meaning of parallelism, and its term is relatively large.

I think there should be that integer, or the kind that is not divided enough, that is, wireless non-cyclic decimals.

If it goes well, you can see if there are two decimal places.

This, it seems, is that the first, and the third, are both true fractions

This society is classified according to the results, and you can learn about the process specifically.

1 out of 3, you see the second level to classify me, and you also go to find a special math teacher to explain it.

Vertical 99

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: Because the divisor is not an integer, first convert the divisor to an integer of 18; The dividend is simultaneously multiplied by the same multiplier: 990

Step 2: 99 18=5 The remainder is: 9

Step 3: 90 18=5 The remainder is: 0

According to the above calculation steps, the combination result quotient is 55 and the remainder is: 0, please ask if you have any doubts, and you are satisfied.

So here you can use the division operation of vertical calculation, and the answer is 55.

1. All addition, subtraction, multiplication and division are mixed operations, you need to calculate multiplication and division first, and then calculate addition and subtraction ==

I'm using an off-form calculation.

The detailed steps of the calculation, written on paper and taken a photo.

Good luck with your learning and progress.

It is easier to do according to the nature of the division.

Problem solving idea: divide each digit of the dividend (from the high position) by the divisor operation, the quotient obtained from each calculation is retained, the remainder + the next digit is calculated, and the divisor is calculated in this order, and the quotient obtained is combined in order, and the remainder is the result of the last operation.

Problem solving process: Step 1: 9 3=3

Step 2: 9 3 = 3

The result is: 33

Check: 33 3 = 99

It only needs to be divided one by one, and it can be divisible, I hope it helps you.
