Mrs. John has 21 lollipops, 28 mochi balls and 49 cupcakes to be placed into the goodie packets.
- What is the maximum number of goodie packets Mrs John needs to pack these items equally into without any left over?
- How many items will there be in each packet?
(a)
Maximum number of goodie packets
= Highest common factor of 21, 28 and 49
= 7
(b)
Number of lollipops in each packet
= 21 ÷ 7
= 3
Number of mochi balls in each packet
= 28 ÷ 7
= 4
Number of cupcakes in each packet
= 49 ÷ 7
= 7
Number of items in each packet
= 3 + 4 + 7
= 14
Answer(s):(a) 7; (b) 14
