Answer:

5 packs of sausages7 packs of rolls

Step-by-step explanation:

You need to find the common multiple.

5 x 7 = 35.

We know that before this there is no other common multiple becuase 7 does not multiply to a number that ends with a 0 or 5 until 35.

So, he will need to buy:

- 5 packs of sausages

- 7 packs of rolls

Answer:

7 packs of rolls

5 packs of sausages

Step-by-step explanation:

The easiest way to solve this question is to make a table with 3 columns

Rolls 5 10 15 20 25 30 35

Sausages 7 14 21 28 35 42 49

# packs 1 2 3 4 5 6 7

Looking at the table you can see that the first number that matches up is 35 so looking at that point we would need 7 packs of rolls and 5 packs of sausages.
