Hey!
454 rounded to the nearest ten is: 450
This is because 4 is less than five, which is why we would round it to 50.
Remember this, DOOP
This stands for decimal, two zeros, then percent.
So, what you do is, since 1.513 is a decimal, you move the decimal two places to the right. You get 151.3
Therefore, 1.513 is 151.3%
A: 3
Good luck on everything
