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%

emember you can do anything to an equaiton as long as you do it to both sides

12x-4y=20
add 4y to both sides
12x+4y-4y=20+4y
12x+0=4y+20
12x=4y+20
minus 20 both sides
12x-20=4y+20-20
12x-20=4y+0
12x-20=4y
divide both sides by 4
12/4x-20/4=4/4y
3x-5=1y
3x-5=y
