Fractional multiplication is a mathematical operation method. The numerator of the fraction is multiplied by the numerator and the denominator is multiplied by the denominator. If you can subtract, you must subtract first, and the numerator cannot be multiplied by the denominator. When doing the first step, we should think about whether the numerator of one number and the denominator of another number can be reduced.

Brief introduction of other situations of fractional multiplication.

The operation method of fractional multiplication: the numerator of the fraction is multiplied by the numerator, and the denominator is multiplied by the denominator. If you can reduce it, reduce it first. When doing the first step, we should consider whether the numerator and denominator of a number can be reduced. A fraction multiplied by an integer is the superposition of several identical numbers.

When a fraction is multiplied by an integer, the numerator is the product of the numerator of the fraction multiplied by the integer, and the denominator remains unchanged. Make an appointment if you can. When a fraction is multiplied by a fraction, the product of numerator multiplication is the numerator, the product of denominator multiplication is the denominator, and the reducible fraction is reduced first.
