What is 345 written as a percent

Answers

Answer: 34500%.

Step-by-step explanation:

When we convert a number into percent , we multiply it by 100.

For example:  To convert 0.56 into percent, we have

0.56*100=56\%

Let's take one more example , to convert 12 into percent , we have

12*100=1200\%

The given number : 345

So to convert 345 into percent , we just multiply it by 100 , we get

345*100=34500\%

Hence, 345 is 34500%.

Thus , the correct answer is 34500%.
I think this is correct 345 = 34500%
