Hello,
To solve this question, a good method to use is creating an equation.
The number x being multiplied by 4 can be represented as 4x.
If this results in 25, we can create the equation:
4x = 25
To solve for x, you want to remove the coefficient of 4 from x, so we can divide by 4 on both sides (doing this we will only get x on the left side of the equation, which is what we are trying to solve for).
So, dividing by 4 on both sides, we have
(4x / 4) = (25 / 4)
x = 25/4
x = 25/4, which cannot be further simplified as a fraction. However, this can be represented by 6.25 in decimal form.
x = 25/4, or 6.25
Hope this helps!
