1/4x2/3= 1/6
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. What can be reduced must be reduced first, and whether the numerator can 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.
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.
Extended data:
First, the operation of fractional multiplication:
1, 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 is multiplied by fraction, numerator is multiplied by numerator, denominator is multiplied by denominator, and the fraction that can be reduced is reduced first.
Divided by two fractions:
1, fractional division is the inverse of fractional multiplication. The calculation rule of fractional division: A divided by B 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.
2, the law of fractional division: Fraction A divided by Fraction B is the reciprocal of Fraction A times Fraction B A/b÷c/d=a/b×d/c, for example?
3. The meaning of fractional division: Like the meaning of integer division, it is the product of two known factors and one of them seeking the other factor. Dividend numerator multiplied by divisor denominator, dividend denominator multiplied by divisor numerator.
