Mike has 12 red marbles. He has twice as many blue marbles as red marbles and 3 times as many yellow marbles as red marbles. San
Mariulka [41]
Ok well, first of all, you must do 12 x 2 because if Mike has twice as many of red marbles, (12 red) then you must multiply that by 2. So 12 x 2 is 24! Then Mike has 3 times as many of yellow marbles, so you do 24 x 3, which is 72! So the answer is A, Sandy is correct. Hope this helps! :)

hot dogs are sold in packages of 10 and hot dog buns are sold in packs of 8 Tommy wants to know the least number of packs of hot
enot [183]

Answer:

4 packs of hotdogs, 5 packs of buns

Step-by-step explanation:

In this case, we need to find the LCM, <em>least common multiple,</em> of 8 and 10 to find the least number of packs of hot dogs and buns that Tommy needs to buy.

The LCM of 8 and 10 is the smallest number that is both divisible by 8 and 10. One way we can find this is by checking all the multiples of 10 in ascending order to see if they are divisble by 8:

10 is not divisible by 8

20 is not divisible by 8

30 is not divisible by 8

40 is divisible by 8!

Therefore, Tommy will need to by 40 buns and 40 hotdogs. Since buns come in packs of 8 and hot dogs come in packs of 10, we can divide to get the number of packs Tommy should buy respectively:

40÷10=4 packs of hotdogs

40÷8=5 packs of buns

<u>Tommy will need to buy 4 packs of hotdogs and 5 packs of buns so that he does not have anything left over.</u>

<em>I hope this helps! Let me know if you have any questions :)</em>
