Calculation method of fractional division

The calculation rule of fractional division: A divided by B (except 0) equals the reciprocal of A multiplied by B.

When the divisor is less than 1, the quotient is greater than the dividend; When the divisor equals 1, the quotient equals the dividend; When the divisor is greater than 1, the quotient is less than the dividend. Multiply the reciprocal of the divisor by the divisor.

The division of fractions can be simply written as one fraction divided by another fraction equals the reciprocal of one fraction multiplied by another fraction.

Mathematical expression: a/b ÷ c/d = a/b× d/c.

For example, we require that 1/2 be divided by 1/3, that is,1/2×1(1/3) =1/2× 3 = 3/2.

Fractional multiplication algorithm:

1. When a fraction is multiplied by an integer, the numerator of the product is multiplied by the numerator of the fraction and the integer, and the denominator remains unchanged. Cut if you can.

2. Fraction multiplied by fraction, numerator multiplied by numerator, denominator multiplied by denominator can be subtracted first.
