(cid:863) (cid:883)(cid:884) (cid:885) means the number of objects in each group when we distribute 12 objects equally among 3 groups. I have 12 candy bars and 3 people. How many would each person get? thirds is equal to 3/8. 3 tons of gravel and it filled my truck full. How much gravel can i put in to fill my truck? the ru(cid:374)(cid:374)i(cid:374)g pro(cid:271)le(cid:373) is a (cid:862)ho(cid:449) (cid:373)a(cid:374)y i(cid:374) o(cid:374)e group?

Then solve the division problem with the aid of a strip diagram, a table, or a double number line. (if you. Running at a steady pace, anna ran 6 miles in (cid:2871)(cid:2872) of an hour. Verify that use a strip diagram, use the strips to show (cid:2871)(cid:2872) of an hour. ) Explain how your solution demonstrates that the problem is solved by multiplying (cid:888) (cid:2872)(cid:2871).
