How do you change 0.452 into a percent?

Hint: To change 0.452 into percent, we have to write the given number in terms of percentage $\left( \% \right)$. We know that if we want to find the percentage then we will multiply this decimal number to 100. So, in this problem, we are going to multiply this given number to 100.

Complete step by step answer:
The number given in the above problem which we are asked to convert into percentage is as follows: 0.452
The number given above is a decimal number so we are going to multiply this number by 100 to convert this number to a percent. Multiplying the above number by 100 we get,
$\Rightarrow 0.452\times 100$
We can write 100 as the second power of 10 in the above expression and we get,
$\Rightarrow 0.452\times {{10}^{2}}$
Now, we know that when we multiply a decimal by some power of 10 then the decimal will shift in the forward direction from its original position with respect to the power of 10 so in the above expression as you can see that power of 10 is 2 so the decimal will be shifted in the forward direction 2 places from its original position.
$\Rightarrow 45.2\%$ $\left( {} \right)$
Hence, we have converted the given number into $45.2$ percent.

Note:
The similar question with a slight twist that could be possible is that we have to find the percent of the following number:
$4.52$
To convert the above number into percent we are going to multiply this number by 100 we get,
$\Rightarrow 4.52\times 100$
On multiplication of the above, the decimal point is shifted two positions forward from the original position then the result of the above multiplication is equal to:
$452\%$
Hence, we have converted the number 4.52 into 452 percent.
