Subject: Re: rounding numbers
Gladys: This is a common question among students young and old. Think of rounding like going up a mountain. Starting at 0 you work your way up the mountain...1,2,3,4 and you hit 5. 5 is the mountain peak and then to go down the mountain you pass 6, 7, 8, and 9. So....to answer your question you need only look at the number in the "ones" position. Which in your case is 8. Because that number is going down the mountain slope, you slide to the next highest number which would be 300. The basic concept is if the number in the ones position is 5,6,7,8, or 9 you would round up. example 273 rounds to 270, 146 rounds up to 150 and so on. I hope this helps !
