5th grade equations and fraction addition and subtraction practice problems

What you need to know about the addition and subtraction of fractions:

1. Same denominator.

Fraction addition and subtraction: The denominator remains the same, only the numerators are added and subtracted.

2. Addition and subtraction of different denominator fractions: first pass the score, and then check and correct the calculation according to the method of addition and subtraction of the same denominator fraction.

3. With scores.

Addition and subtraction: add and subtract with fractions, add and subtract the integer part and the fraction part separately, and then combine the obtained results.

Mastery of multiplication and division of fractions:

1. Multiply fractions by whole numbers.

Fractions are multiplied by integers, and the product of the numerator of fractions and integers is used as numerators, and the offer points that can be reduced to fractions.

2. Multiply fractions by fractions.

Multiply fractions by fractions, use the product of the multiplication of the numerators as the numerator, and the product of the multiplication of the denominator as the denominator. The offer to be able to make a contract. In the first step, it is necessary to consider whether the numerator of one number and the denominator of another number can be divided (except for 0).

3. The fraction is divided by the collapse of the mountain as an integer.

The fraction is divided by an integer, the denominator does not change, if the numerator is a multiple of an integer, the numerator is divided by the integer, and finally it is not the simplest fraction.

To make it into the simplest fraction.

4. Divide the fraction by the fraction.

Fraction division. Convert to fraction multiplication.

Dividing one fraction by another fraction is equal to multiplying the reciprocal of this fraction, and an integer can be transformed into a false fraction with a denominator of 1.
