1 How much is 4 yuan into the simplest fraction

The fraction in which the numerator and denominator are coprime numbers is called the simplest fraction (the simplest fraction is also called the reduced fraction). Let's take a look at the three current situations of the problem of "reducing to the simplest": 1. Students don't understand what the simplest fraction isStudents often don't understand why they want to reduce to the simplest form, and don't know what the simplest form is, such as:

27 3 etc. The student will rightly assume that this is the final result, and ask the student why, and the student will feel that this is the final result. Suggested resolution:

In the learning process, it is necessary to pay attention to the learning of basic knowledge and basic concepts. 2. Students are better at multiples of equals, but worse on multiples of equals, and the third unit is mainly studied in the fifth grade, and the basis for the reduction is the first unit in the fifth grade. Whether it is from the teaching objectives or the textbook, students learn multiples, but for the multiples of other numbers, there is no special study and practice, so when it comes to these values, students have a poor grasp of these values.

Solution: Usually do more multiplication of equal numbers. 3. Students do not have the habit of reducing points when doing calculation problemsIf students are asked to do the special topics, students do better, but students always forget to reduce points when they usually do homework and calculations, and the mathematics teacher believes that "students have just learned, and they have not formed a habit of reducing points, and they have not formed a subconscious mind of reducing points".

Solution: Make a habit and start by forcing yourself. The results are checked every time you finish the question to see if you can get a score.

Reduction runs through the study of mathematics, and the idea of reduction is also an important idea of mathematics. Next, let's take a look at what we need to learn from elementary school to university: In the fourth grade of primary school, students learn division, and the most important property is:

The quotient remains the same. Example: 4000 125 = (4000 8) (125 8) = 32000 1000 = 32 The quotient invariant property is also the inverse of the use of the fifth grade of primary school, when the fifth grade of primary school is the fifth grade, I learned to reduce the score.

How exactly is the covenant made? Is it simply crossed out with a line? Of course not!

In fact, it uses the familiar division method, which is actually the numerator and denominator divided by an identical number at the same time. Why use the numerator and denominator to remove the same number instead of subtracting the same number, and on what basis? It can be understood as turning a fraction into a fraction that is equal to it, but the numerator and denominator are smaller, which is called a fraction.

When I was in the sixth grade of elementary school, I learned about ratios and ratios, and at this time, the objects that need to be divided were changed from integers to decimals, and the reductions were also reflected in ratios and ratios.

1 and 2/5 dollars.

The simplest fraction is 2 to 5. Because the decimal is transcribed as a fraction, look at how many decimal places there are, so. Simplification is a basic operation that is often encountered in mathematics learning, so what are the skills of simplification?

Decimal fraction: see how many decimal places there are after the decimal point, add a few 0s as the denominator after 1, and remove the decimal point as the numerator, and then the offer score can be reduced. Fractionalization: You can divide the numerator directly by the denominator.

In general, in the process of simplification, decimals are treated as whole numbers when reducing minutes. Then, according to the basic properties of the fraction, the numerator part and the denominator part of the fraction are multiplied by integers, and then the result is calculated by cross-reduction, and the final result can be obtained by reducing the fraction on this basis.

The above is the decimal fraction, fractional skills and methods, learning to simplify is the necessary foundation for us to learn mathematics, I believe that we can master simplification through the above simplification method introduction, the learning of mathematics is also simpler.

The simplest fraction is 9 2000.

It can be converted to a fraction of 45 10000 and then simplified to 9 2000. Hope.

Solution: Determine whether the numerator denominator is 1, if it is 1, it is the simplest fraction, if it is not 1, you can use the largest common factor to simplify the numerator denominator.

It can be seen as a sum of 4, and the fraction of formation is one-twentieth, and when combined with a four, the answer is four-and-twentieth.

The simplest fraction is: 6 5

6 and 5 are coprime numbers, so the simplest fraction is 6 5

A fraction whose numerator and denominator are coprime numbers is called the simplest fraction. The numerator and denominator of the fraction of the simplest fraction have no common divisor other than 1. The simplest fraction is also called the reduced fraction, and the fraction can be understood as the fraction that has been reduced, that is, the fraction whose numerator and denominator are coprime numbers.

The simplest fraction is a fraction in which the numerator and denominator have only a common factor of 1, or a fraction in which the numerator and denominator are cogenetic, also known as a reduced fraction.
