Fractional Multiplication 100 Channel with Answer

Integer decimal multiplication

2/ 1X8= 16

5/8X4=5/2

6/5X5=6

8/7X7=8

6/5Ⅹ 10= 12

Score times score.

1/2X6/5=3/5

1/7Ⅹ7/5= 1/5

1/7X 1/8= 1/56

8/9X2/7= 18/63

1/22X22/4= 1/4

Divide the score by the score.

5/4÷2/7=35/8

2/3÷8/ 16=3/4

8/6÷6/7= 14/9

1/22÷4/22= 1/4

5/2÷2/5=25/4

4.4/5×3/4=3/5

5.8/7× 1/2=4/7

6.3/5×5/8=3/8

7.6/7×3/2=9/7

8.5/6×8/3=20/9

9.4/ 1 1×3/4=3/ 1 1

10.4/9×3/8= 1/6

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.

Extended data:

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. Multiplying a fraction by an integer is the superposition of multiple identical numbers, such as

X2 means two additions, and X 10 means 10 additions.
