help please One slice of cheese pizza contains 290 calories. A medium-size orange has one-fifth that number of calories. How many calories are in a medium-size orange?
|dw:1342414334634:dw| Do you know division?
So if the orange has one-fifth the number of calories of the pizza, then if you divide the calories of the pizza into five equal amounts of calories, the orange has only one of those amounts of calories. |dw:1342414718201:dw| So 290 calories divided up into 5 parts is 58 calories each part...the orange only has 1 out of 5 of that amount of calories, so one orange has 58 calories
