Question

Sally has 243.75 pieces of candy. John has 27.4 pieces of candy. How many pieces of candy do they have in all? John thinks altogether there are 217.15 pieces of candy. Is he correct? Explain your thinking.

Answer 1

Answer:

271.15

Step-by-step explanation:

     1 1

  243.75

+    27.4

___________

         271.15  

I think the reason why he thought altogether they would have 217.15 is because he probably did not align them correctly. He might have even

flip-flop the 7 and the 1.

Answer 2

Answer:

Yes, John is correct.

Step-by-step explanation:

To find the total amount of candy you must add the amounts Sally and John have. Sally has 243.75 and John has 27.4. When you add those two together you can 217.5 which is what John thinks therefore he is correct.
