Question

Sausages come in packets of 12. Bread rolls come in packets of 9. 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

Answer: packet of sausage = 3, packet of roll = 4

Step-by-step explanation:

I do guess and check.

12(1) + 9(1) = 12 + 9
12(2) + 9(2) = 24 + 18
12(3) + 9(3) = 36 + 27
12(3) + 9(4) = 36 + 36

So that’s the answer
