Ms. jones= 18 pencils she gave her pencils to 6 sudent.
this is one of how you have your answer:
if jones has 6 pencils and she gave it to six student, each student will have 1 each right? okay if jones has 12 pencils and she gave it to the students, each student will have 2 each because you just doubled the 6 it became 12.
if jones has 18 pencils and gave it to 6 student each student will have 3 each, because you tripled the 6 it became 18. so the answer is 3, ms. jones gave the students 3 each
hope this helps!! :))
