In the sixth grade mathematics book, use simple method to calculate the following questions, and talk about the law of operation
Use a simple method to calculate the following problems, and say what laws are used
2 / 3 times 1 / 4 times 3
2. (8 / 9 + 4 / 27) times 27
3.87 times 3 / 86
Out of form calculation

1. Two thirds multiplied by three and then multiplied by one fourth equals one half {commutative law of multiplication}
2. 8 / 9 times 27 + 4 / 27 times 27 equals 28 {law of multiplicative distribution}
3. {86 + 1} times 3 / 86
Equal to 86 times 3 / 86 + 1 times 3 / 86 equals 3 and 3 / 86 {law of multiplicative distribution}
