Question

Mr. haigwood is shopping for a school picnic . veggie burgers comes in packages of 15 and buns come in packages of 6. he wants to serve veggie burgers on buns and wants to have no items left over. Mr. haighwood says that he will have to buy at least 90 of each item 6 x 15 =90. Do you agree with his reasoning

Answer 1

No, to find the least number of burgers and buns, you should find out the LCM of 15 and 6, not their product.

LCM = 30,
so they need to buy atleast 30 of each item.

Answer 2

Mr. haigwood is not right.

Explanation:

The veggie burgers comes in packages of 15 and buns come in packages of 6.

Mr. haigwood wants to serve veggie burgers on buns and wants to have no items left over.

Now, to find the least number of burgers and buns needed so nothing is left over, we will find the LCM of 15 and 6.

15 = 3 x 5

6 = 2 x 3

LCM = 2 x 3 x 5 = 30

As given, Mr. haighwood says that he will have to buy at least 90 of each item 6 x 15 =90.

This is not right. He needs to buy at least 30 of each item so that nothing is left over.
