Dani manages a charter boat business. She has these fishing lures for 3 boats. She wants to put the same number of lures on each boat. How many lures should Dani put on each boat?
Answer:
Dani manages a charter boat business.
She has these fishing lures for 3 boats.
She wants to put the same number of lures on each boat.
Total lures = 4 x 10 + 8 = 48
So, 48 ÷ 3 =
Dani put 16 lures equally on each boat.
Show your thinking.
Turn and Talk Why does Dani need to open one package of lures in order to divide all the lures equally?
Answer:
In order to get equal lures for each boat, she has to open one package of lures. Because 4 packets i.e., 4 x 10 = 40 can not be shared equally, one lure will be remained after sharing 39, 39 = 3 x 13. So, she has to open one package of lures in order to divide all the lures equally.
