  3. A florist has 36 roses, 27 tulips, and 18 carnations she must use to create bouquets. What is the largest number of bouquets she can make without having any flowers left over?   

  4. The HCF is the number we're looking for, the remaining factors in each number tell us how may of each to put in each bouquet. • roses: 36 = 22x 32 • tulips: 27 =  33 • carnations: 18 = 32 HCF  = 32 = 9 bouquets    (smallest exponent of 3 is 2) each bouquet will have     • roses:  36 : 9 = 4 • tulips:  27 : 9 = 3 • carnations:  18 : 9 = 2

  5. Say you have 60 pencils, 90 pens and 120 books and you want to make packages of pencils, pens and books to donate to your school for students who cannot afford these supplies.  What is the maximum number of packages you can make using all items, and how many pencils, pens and books will be in each package?

  6. pencils: 22x 3 x 5 • pens: 2 x 32x5 • books: 23x3x5 • HCF        = 2  x  3  x 5   = 30 packages content of each package  • Pencils = 60 : 30 = 2 pencils • Pens = 90 : 30 = 3 pens • Books = 120 : 30 = 4 books • Each package with 2 pencils,  3 pens, and 4 books  in each package.

  7. Try this! Dean baked 30 oatmeal cookies and 48 chocolate chip cookies to package in plastic containers for her friends at school. She wants to divide the cookies into identical containers so that each container has the same number of each kind of cookie.

  9. You and your three friends go to lunch and find a deal on packages of 6 tacos.  You want to buy the minimum number of packages so you each get the same number of tacos and none are left over.  How many packages must you buy? the LCM of 4 and 6? 4 = 22 6 = 2 x 3  LCM = 22x 3 = 12.   12 tacos requires 2 packages and you each will get 3 tacos.  

  10. One trip around a running track is 440 yards.  One jogger can complete one lap in 8 minutes, the other can complete it in 6 minutes.  How long will it take for both joggers to arrive at their starting point together if they start at the same time and maintain their jogging pace? 

  11. LCM of 6 and 8? 6 = 2 x 3 8 = 23 LCM   =  23x 3 = 24 minutes • the slower jogger will have completed   3 laps    ( 24 : 8 = 3) • the faster jogger will have completed 4 laps ( 24 : 6 = 4)

  12. Try this! Bridget has swimming lessons every fifth day and diving lessons every third day. If she had a swimming lesson and a diving lesson on May 5, when will be the next date on which she has both swimming and diving lessons?
