The fourth grade division calculation problem is a little more difficult.

The fourth-grade division equations are:

Division calculation method1. Long division.

Long division, commonly known as long division, is suitable for integer division, decimal division, and polynomial division.

i.e. factorization.

Emphasis is placed on the calculation process and the division of quotients, and both multiplication and subtraction are used in the process.

According to the multiplication table, two integers can be calculated with a long division (straight division) pen. If the dividend.

There is a fractional part (or decimal point), and the decimal point can be brought down when calculating; If the divisor has a decimal point, shift the divisor at the same time as the decimal point of the dividend until the divisor has no decimal point. Abacus.

You can also do division operations.

2. Short division.

Short division is commonly known as short division, which is suitable for fast division and simultaneous division of multiple integers (so it is often used to find the greatest common factor.)

and least common multiples), binary digit conversion, etc., pay more attention to multiple tests and prime factors.

Multiplication), most of the process only needs to answer the multiplication factor of the multiplication table and a few integers above 9.

1. In the case of equal distribution, division will be used. Such as:

There are a total of 10 pieces of candy, divided equally among 5 children, how many pieces of candy can each child get?

2. When finding percentages, division is also used. Such as:

A company had a total revenue of 1 million yuan last year and a total revenue of 1.1 million yuan this year, so how much higher was the revenue growth rate last year?

3. Accounting also needs to use division when calculating costs. Such as:

A hotel restaurant has a cumulative sales of 1 million yuan in food sales in March, and the cost of various ingredients and seasonings is 600,000 yuan, so what is the food cost rate of the restaurant in March?

4. Divisions are also used in the various formulas studied in the basic physics and chemistry courses. Such as:

Newton's formula for gravitational force, energy conservation formula, electron conservation formula, mass conservation formula, etc.

Dividend = divisor x quotient + remainder.

Dividend = 4 x divisor + 8

Dividend + Divisor + Quotient + Remainder = 415

4x divisor + 8 + divisor + 4 + 8 = 415

5x divisor = 395

Divisor = 395 5

Divisor = 79 Dividend = 79x4 + 8 = 324

1. Grandpa Wang's 4 cows produce 896 kg of milk per week. How many kilograms of milk does an average cow produce per day?

The car was empty and lurked three times, carrying 960 bags of water and mud. How many bags of cement does each car transport at a time?

A swallow can eat 480 pests in 4 days, how many pests does each swallow eat per day on average?

4. An owl can eat 42 voles in a month, and how many voles can 15 owls eat in a year?

These are all fourth-grade starting application questions, I hope it can help you.

Good luck with your studies.

The fourth-grade division equation is as follows:

Division calculation method1. Long answer early division.

The Changqing Bird Dividing Method, commonly known as long division, is suitable for integer division, decimal division, polynomial division (i.e., factorization) and other divisions that pay more attention to the calculation process and quotient, and use both multiplication and subtraction in the process.

According to the multiplication table, two integers can be calculated with a long division (straight division) pen. If the dividend has a fractional part (or a decimal point), it is enough to bring the decimal point down when calculating; If the divisor has a decimal point, shift the divisor at the same time as the decimal point of the dividend until the divisor has no decimal point. The abacus can also do division operations.

2. Short division.

Short division, commonly known as short division, is suitable for fast division, simultaneous division of multiple integers (so it is often used to find the greatest common factor and the least common multiple), binary digit conversion and other divisions that pay more attention to the multiple test and prime factor (multiplication), and most of the process only needs to use the multiplication factor of 99 multiplication table and a few integers above 9.

Fourth-grade three-digit division by two-digit division is multi-digit division.

Example questions have a draft:

The rule of multi-digit division:

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

2) Divide to which digit of the divisor of the hall, 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.

The division practice questions in the first volume of the fourth grade are highlighted.

5.There are a total of 73 1 yuan coins. How many coins can I exchange for $10 bills? What if you exchange it for a $20 bill?

It is understood that the fourth-grade division is calculated like this:
