The basic operations with fractions are addition, subtraction, multiplication and division.

Addition: adding fractions with the same denominator, the denominator does not change, i.e. the fractional unit does not change, the numerator is added, can be divided to divide.

Adding fractions with different denominators, that is, converting fractions with different denominators into fractions with the same denominator using the basic properties of fractions, changing the unit of the fractions without changing the size, then adding fractions with the same denominator to calculate, and finally dividing those fractions that can be divided.

Subtraction operation: Subtract the fraction with the denominator that is the result of subtracting the numerator as the numerator, leaving the original denominator unchanged.

To subtract fractions with different denominators, first divide and then calculate according to the rule for subtracting fractions with the same denominator.

Multiplication: multiplying the numerator of the fraction by the numerator, multiplying the denominator by the denominator, and dividing what can be divided.

To multiply a fraction by an integer is to put several identical numbers on top of each other.

Division: Fractional division is the opposite of fractional multiplication. Fractional division rule: A number divided by B number (except 0) is equal to A number multiplied by the reciprocal of B number. If the divisor is less than 1, the quotient is greater than the dividend.

Once you have mastered these operations, you can move on to more complex fractional operations.
