Answer：
In an arithmetic expression without parentheses, when there are only multiplication and division operations, which are operations of the same level, they are calculated in order from left to right.
- First, calculate 4×5=20. Then the expression becomes 20÷5×4.
- Next, calculate 20÷5=4. Then the expression becomes 4×4.
- Finally, calculate 4×4=16.
So, 4×5÷5×4=16.
