7 10 minus 3 5? 7 10 minus 3 4 minus 2 5 A few fractions

Hello, this question is calculated according to the subtraction operation of fractions:

Original = 7 10-6 10 = (7-6) 10 = 1 10, so the result is equal to 1 out of 10.

Expand your knowledge: How to calculate fractions.

1. Addition and subtraction of fractions.

If it is the same denominator fraction, the denominator remains unchanged, and the numerators are added and subtracted. If it is a different denominator score, it will be scored first, and then calculated according to the addition and subtraction of the same denominator fraction. The unit "1" is divided into several parts, and the number of such parts or several of them is called a fraction.

The number that represents such a part is called the fractional unit. Fractions are divided into false and true fractions. False fractions are further divided into banded fractions and integers.

The numerator and denominator are coprime, and this fraction is called the simplest fraction. To decimalize the fraction, see how many decimal places it is, to determine the denominator, and then look at the number after the decimal point, that is, the numerator, if there is an integer, it becomes a fraction.

2. Fraction multiplication and division.

The numerator of the fraction is multiplied by the numerator, the denominator is multiplied by the denominator, and the numerator cannot be multiplied by the denominator. The calculation method of fraction multiplication and division includes fraction multiplication by integer, denominator unchanged, numerator multiplied by integer, and finally the offer fraction that can be reduced.

Notes on scores:

1. The denominator must not be 0, because the denominator is equivalent to the divisor. Otherwise, the equation cannot be held and the numerator can be equal to 0 because the numerator is equivalent to the dividend. It is equivalent to 0 divided by any number, regardless of the denominator, the answer is 0.

2. The numerator or denominator in the fraction cannot appear irrational numbers (such as the square root of 2) after reduction, otherwise it is not a fraction.

3. Only two prime factors, 2 and 5, can be reduced to finite decimal numbers in the denominator of a simplest fraction; If the denominator of the simplest fraction contains only prime factors other than 2 and 5, then it can be reduced to a pure cyclic decimal; If the denominator of the simplest fraction contains both prime factors of 2 or 5, as well as prime factors other than 2 and 5, then it can be reduced to a mixed cyclic decimal.

= 14/20 - (15/20 - 8/20) = 14/20 - 7/20

7 out of 20

Kiss, the calculation method of fraction addition and subtraction is the first minute, the denominator is the same, and the numerator is added and subtracted.

Can 19 70 be simplified.

19 is a prime number, only the factor 1, 19, and 70 have no common factor.
