Question

two brands of pencils are available in packs of 15 and 25 respectively. henry wants to buy an equal number of pencils of both kinds. what is the least number of boxes of each kind henry needs to buy?

Answer 1

Step-by-step explanation:

Given, two brands of pencil are available in pack of 24 and 15 respectively.

We need to buy an equal number of pencil of both kinds.

For this we find the LCM of 24 and 15

Now,

24=2 3×3

15=3×5

LCM(24,15)=2 3 ×3×5=120

Now,

the number of boxes of pack of 24 = 120/24=5

and the number of boxes of pack of 15 = 15/120 =8
