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. W

Sergeu [11.5K]

Answer:

Greatest sack = 42

1 candy bar and 3 lollipops

Step-by-step 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:

$Treats = \frac{C}{GCF}$

$Treats = \frac{42}{42}$

$Treats = 1$

For L:

$Treats = \frac{L}{GCF}$

$Treats = \frac{126}{42}$

$Treats = 3$

Hence, 1 candy bar and 3 lollipops
