Question

Sausages come in packets of 12. Bread rolls come in packets of 4. Brian wants to buy enough packs of sausages and rolls so that there are an equal number of sausages and rolls. What is the minimum number of sausages and rolls he needs to buy?

Answer 1

He needs to buy a minimum of 1 packet of sausages and 3 packets of rolls.

Given:

Sausages come in packets of 12. Bread rolls come in packets of 4. Brian wants to buy enough packs of sausages and rolls so that there are an equal number of sausages and rolls.

To find:

The minimum number of sausages and rolls he needs to buy

Step-by-step explanation:

• In order to find the minimum number of sausages and rolls he needs to buy, we find the LCM of 12 and 4.

Here,

• 12 = 2 × 2 × 3
• 4 = 2 × 2

So, LCM = 2 × 2 × 3 = 12

Number of packets of sausages = 12 ÷ 12 = 1

Number of packets of rolls = 12 ÷ 4 = 3

So, he needs to buy a minimum of 1 packet of sausages and 3 packets of rolls.
