Acarton holds 24 bottles of juice how many juice bottles are in 15 cartons

We know that a carton holds 24 bottles of juice and we want to find out how many juice bottles are in 15 cartons. To solve this problem we have to use multiplication.  

24 * 15 = # of juice. 



Set up the long multiplication.

Calculate 4 x 5, which is 20.

Since 20 is two-digit, we carry the first digit 2 to the next column.

Calculate 2 x 5, which is 10. Now add the carry digit of 2, which is 12.

Since 12 is two-digit, we carry the first digit 1 to the next column.

Bring down the carry digit of 1.

Calculate 4 x 1, which is 4.

Calculate 2 x 1, which is 2.

Calculate 120 + 240, which is 360

Therefore, 24 x 15 = 360.
