5. For a science experiment in Mr. Thomas’s 3rd grade class, each student needs 8
   milliliters of water. If there are 23 students in Mr. Thomas’s class, how many milliliters
   will be needed in all?
   Answer:

To find the total amount of water needed, you simply multiply the number of students by the amount of water each one requires. So, you’d calculate . Mr. Thomas will need a total of 184 milliliters of water for the experiment!

Now, remember to check your multiplication! A common mistake is accidentally forgetting to carry over numbers or misplacing decimals. Always double-check your math to ensure you have the correct amounts for your experiment - you wouldn’t want to end up with too little or too much water!
