Research and solve:

This is a question about multiplication and division of fractions. You should pay attention to the following during operation:

① Operate according to the algorithm;

② Multiplication and division operations are operations of the same level, and should be calculated according to the principle of first appearing first, and the order of operations cannot be exchanged;

③When division is written in the form of multiplication, flexible application of the commutative law and associative law of multiplication can simplify the operation;

④The result must be written in the form of an integer or the simplest fraction.

Obviously there is an error in the order of operations in this question. The associative law cannot be used unless it is converted into multiplication. Everyone should keep this in mind!

The characteristics of mixed operations: it is a comprehensive application of integer operations, factorization, and fraction operations. It is highly comprehensive and is the focus and difficulty of learning in this chapter.
