Because of the commutative property of multiplication, it is true that 3/4×4 = 4×3/4
. However, these expressions can be calculated in different ways even though the solutions will be the same.
Below, show two different ways of solving this problem.
First, show how 3/4×4
can be solved using repeated addition.

Question 2
Then, show how 4×3/4
can be solved using multiplication and division.
(2 points)
First, let's solve 3/4 × 4 using repeated addition:
To do this, we can add 3/4 four times.
3/4 + 3/4 + 3/4 + 3/4 = 12/4
Simplifying 12/4, we get 3.
Now let's solve 4 × 3/4 using multiplication and division:
First, we multiply 4 by 3, which gives us 12.
Then, we divide 12 by 4, which gives us 3.
So, 4 × 3/4 equals 3.

To find the side length of the square, we need to take the square root of its area.
Taking the square root of 1636, we find that the side length of the square is 40 ft.
None of the given options match the correct answer of 40 ft, so none of the listed options show the side length of the square.
