Johnny had 12 apples but he ate 11 ½, then he bought 2 ½ pounds of apples how many apples does he have left? 1 pound = 10 apples
For our first question on the quiz.
12-11.5+2 1/2 lbs 1 lbs=10 apples
OK first, you can combine like terms, 12-11.5 that = .5 apples the you have to do .5+2 1/2 lbs
OK now we have to convert the pounds to how many apples there are. If there are ten apples per pound and we have 2 1/2 pounds then how many apples did he buy? well we have 2 full pounds so that is 20 apples but then we have a half and that is 5 apples so we have to do 20+5 and that equles 25 apples. so since we had .5 apples and we have 25 apples we have to add them together and the makes 25.5 apples!
