Question

When a number x is multiplied by 4, the result is 25 .

Answer 1

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!

Answer 2

The answer is 6.25

Let's test this out:

6 * 4 = 24 + (0.25*4) = 25
