Question

Emma buys packets of coloured beads
purple beads are sold in packets of 8
red beads are sold in packets of 5
blue beads are sold in packets of blue
Emma wants to buy an equal number of purple read and blue beads
what is the smallest number of each colour emma could buy

Answer 1

Answer:

40

Step-by-step explanation:

Given,

The number of purple beads in the packet = 8,

While, the number of red beads in a packet = 5,

Thus, the smallest number of beads of each color = LCM(8, 5),

∵ 8 = 1 × 8,

5 = 1 × 5

⇒ LCM(8, 5) = 40,

Therefore, the smallest number of each color she could buy would be 40.

Answer 2

Answer:

40

Purple:5

Red:8

Blue:4

Step-by-step explanation:

List the multiples of 8,10 and 5

8,16,24,32,40,48,56,64,72,80,88,96,104

5,10,15,20,25,30,35,40,45,50,55,60

10,20,30,40,50,60,70,80,90,100

your trying to find LCM in all of them and that is 40.

After that you count how many packets there are with each multiple.

The correct packets are listed above.

And yeah thats it.
