5(4+1) ÷ 5(5) = 20/25
You can simplify the expression by first performing the operations inside the parentheses.
So, 5(4+1) becomes 5*5 which is 25.
Then 25 ÷ 5(5) becomes 25/25 which is 1.
Therefore the final answer is 1.
Note: The order of operations is important, you have to perform the operations inside the parentheses first, then the multiplication and division.
