Nearest tenth it would be <em><u>360</u></em><em><u /></em><u /> because the ones digit (3) is less than 5 so we have to round down.
Nearest hundred would be <em><u>400</u></em><em><u /></em><u /> because the tens and ones digit (63) is closer to 400 than it is to 300. So we would have to round up.
Hope that helps :)
The CPU speed determines how many calculations it can perform in one second of time. The higher the speed, the more calculations it can perform, thus making the computer faster.
