Fill in the missing number. 20% of = 5
Understand the Problem
The question is asking us to find the missing number that, when we take 20% of it, equals 5. This involves basic percentage calculations where we can set up the equation 0.2 * x = 5 and solve for x.
Answer
25
Answer for screen readers
The missing number is $25$.
Steps to Solve
- Set up the equation
We know from the problem that 20% of a number $x$ equals 5. The percentage can be converted into decimal form, so we have:
$$ 0.2 \cdot x = 5 $$
- Isolate the variable
To solve for $x$, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.2:
$$ x = \frac{5}{0.2} $$
- Calculate the value of x
Now, we can perform the division:
$$ x = \frac{5}{0.2} = 25 $$
The missing number is $25$.
More Information
This means that when you take 20% of 25, you indeed get 5. This type of problem is common in basic algebra and percentage calculations.
Tips
- A common mistake is forgetting to convert the percentage to its decimal form before performing calculations. Always remember to convert percentage to decimal: for example, 20% becomes 0.2.
