What is 4 (5×1÷20) because I dont know lol
Whitepunk [10]
Well first we need to do whatever is in the parentheses, which in this case is: (5x1/20)

Following the order of operations (PEMDAS) we start with the multiplication, which is (5x1). We know that 5x1=5, so now we can move on to the division:

5/20, which is equal to 0.25

So now that we know the answer to the equation in the parentheses is 0.25, we can solve the whole equation.

Here is the equation simplified:

4 (0.25)

Because there is now operation indicated between the 4 and the parentheses, we can assume that multiplication is implied, so the final equation is as follows:

4x0.25=1

The final answer is: 1

Hope this helps!
