Question

6. Steve is packing sacks for treats at a party. Every sack is exactly the same. Steve has 42 candy bars and 126 lollipops. a. What is the greatest number of treat sacks Steve can make? b. How many of each kind of treat is in one sack?

Answer 1

Greatest sack = 42

1 candy bar and 3 lollipops

Explanation:

Represent Candy bars with C and Lollipops with L

`C = 42`

`L= 126`

Solving (a): Greatest number of treat sacks

To solve this, we simply calculate the GCF of C and L

`42 = 2^1 * 3^1 * 7^1`

`126 = 2^1 * 3^2 * 7^1`

Hence, the GCF is

`GCF = 2^1 * 3^1 * 7^1`

`GCF = 42`

Hence, greatest number of sack is 42

Solving (b): Number of treat in each sack.

To do this, we simply divide the number of C and L by the calculated GCF

For C:

`Treats = (C)/(GCF)`

`Treats = (42)/(42)`

`Treats = 1`

For L:

`Treats = (L)/(GCF)`

`Treats = (126)/(42)`

`Treats = 3`

Hence, 1 candy bar and 3 lollipops
