4 of what number is 5?
Understand the Problem
The question is asking us to find the number 'x' such that 4 times 'x' equals 5. This can be solved by setting up the equation 4x = 5 and then solving for x.
Answer
The value of \( x \) is \( \frac{5}{4} \).
Answer for screen readers
The value of ( x ) is ( \frac{5}{4} ).
Steps to Solve
- Set up the equation
We start with the equation given in the problem:
$$ 4x = 5 $$
- Isolate 'x'
To solve for 'x', we need to divide both sides of the equation by 4:
$$ x = \frac{5}{4} $$
- Simplify the fraction
Now, simplify the fraction if possible. In this case, it is already in its simplest form.
The value of ( x ) is ( \frac{5}{4} ).
More Information
The number ( \frac{5}{4} ) is also equal to 1.25 in decimal form. This problem illustrates the process of isolating a variable by using inverse operations, which is fundamental in algebra.
Tips
- Forgetting to divide both sides by the same number, which can lead to incorrectly solving for 'x'.
- Misreading the problem setup and not recognizing that the equation should be manipulated correctly.
