For a party 20 sandwiches are being made if each sandwich is cut into thirds how many sandwich pieces are there?

There would be 60 sandwich pieces.

20 times 3=60

Well let’s simplify the problem.

If we take one sandwich it would be 1: and if we add the fact that for every one sandwich 3 new sandwiches were made, we can make a 1:3 ratio. If for every 1 sandwich there are 3 more sandwiches then we would multiply the beginning amount of 20 sandwiches to both numbers in the ratio so it stays equivalent.

1 x 20 = 20

3 x 20 = 60

So we can say now that the ratio for 20 sandwich pieces there are 60 new sandwich pieces.

The new ratio being 20:60 thus the amount of sandwiches after they were cut in thirds is 60 sandwiches

Answer = 60 sandwiches
