For a large cooking project, Arthur needs to put 18 cups of water into a large pot. He can transport a maximum of 4 cups from the sink in a single trip. The pot already contains 5 cups of water. How many trips are required for Arthur to fill the pot to 18 cups?

Respuesta :

Step 1 find out how many cups of water is left
18-5=13
step 2 divide 13 by 4 to figure the number of trips
13/4=3.25
step 3 you cant make a quarter trip and you still need that quarter cup so you round up
3.25 = 4 trips 
step 4 finished
