Answer 2

The right answer is six packages of hot dogs and five of buns to get 60packages of hot dogs and 60 of buns.

Explanation:

we can do this exercise using the least common multiple or "LCM" for ten and twelve.

First of all, we need to find the LCM for 10

LCM for 10:

10: 10, 20, 30, 40, 50,60 70,80,90,100.

And now for 12

LCM for 12:

12: 12, 24, 36, 48, 60, 72,84,96, 108,120.

we can see that 60 is a common multiple for 10 and 12.

Finally, we need to divide 60 between 10 and 12 to find the number of packages that Martha needs to buy to buy

60/10= 6 we know that hot dogs come in packages of 10 so we need to buy 6 packages of hot dogs

60/12=5 we know that hot dogs come in packages of 10 so we need to buy 5 packages of buns

So
