Answer 2

How many pencils would be required to make complete sets of 12, 15 and 20?

Given,

Sets of 12, 15 and 20

To find,

Number of pencils required to make complete sets

Solution,

To find the number of pencils required to make complete sets of 12, 15 and 20, we need to find a number that is a multiple of all 3.

Therefore, we need to find the LCM of 12, 15 and 20.

Multiples of 12 = 12, 24, 36, 48, 60, 72...

Multiples of 15 = 15, 30, 45, 60, 75, 90...

Multiples of 20 = 20, 40, 60, 80, 100...

So, Least Common Multiple = 60

60 pencils would be required to make complete sets of 12, 15 and 20.
