The sixth grade fractional multiplication is a mathematical operation method in sixth grade. 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. (except 0)

Multiplying a fraction by an integer is to add up multiple identical numbers, for example? X2 means two? Add it up? X 10 means 10? Add it up. If the integer is multiplied by the fraction: the integer is multiplied by the numerator, not the denominator (both integer and denominator can subtract a fraction). Here, multiplying a number by a fraction means finding a fraction of this number.

1, when a fraction is multiplied by an integer, the product of the numerator of the fraction multiplied by the integer is taken as the numerator, and the denominator remains unchanged. Make an appointment if you can.

2. When a fraction is multiplied by a fraction, the product multiplied by the numerator is the numerator and the product multiplied by the denominator is the denominator. If the score can be lowered, you can lower the score first.

3. When a fraction is multiplied by a decimal, you can convert the fraction into a decimal, or you can decompose the decimal into components and simplify the fraction first.
