What number can replace x to demonstrate the commutative property of multiplication

25x = 4 . 25

To demonstrate the commutative property of multiplication, we need to find a value of x that satisfies both equations: 25x = 4 and 4 * 25 = 25x.

First, let's solve the equation 25x = 4 to find the value of x:
Divide both sides of the equation by 25:
25x/25 = 4/25
x = 4/25

Now, let's substitute this value of x into the second equation 4 * 25 = 25x:
4 * 25 = 25 * (4/25)

Multiplying the fractions:
100 = 100

Therefore, x = 4/25 can replace x to demonstrate the commutative property of multiplication.
