Whats the last common multple of 2,5,6,9 and 9 is
blondinia [14]
"9 and 9?"  Did you possibly mean {2, 5, 6, 9}?

The least common multiple of a set of numbers is the smallest integer that can be divided evenly by all of the numbers.  In this case, when I saw the 9 and 5, I thought, "45!"  but 45 is not evenly divisible by 2 or 6.  

So, I tried 90.  90 is indeed divisible by {2, 5, 6, 9}, and is thus the LCM.

Look up and review "Least common multiple."

Kisachek [45]

Ryan isn't correct.

Step-by-step explanation:

If Ryan wants to make exactly 3 cups of dip, he would need 3/8 pounds of chicken.

1/8(3)=3/8 pounds.

3/4, or 6/8 pounds of chicken doesn't represent 3 cups, it's for 6 cups of dip.

The dimensions would have to be 20 x 5 as the model holds the same amount for each side, and because 5 is larger than 4 its used as the models stand.
