Lucia is making invisibility potions. Each potion requires 222 eyes of newt. How many invisibility potions can Lucia make with 161616 eyes of newt? Lucia has all of the other ingredients she needs.

Answer 1

We have been given that Lucia is making invisibility potions. Each potion requires 2 eyes of newt. We are asked to find the number of invisibility potions that Lucia can make with 16 eyes of newt.

We will use proportions to find the number of potions that Lucia can make with 16 eyes of newt as:

$\frac{\text{Invisibility potions}}{\text{Number of Newt eyes}}=\frac{1}{2}$

$\frac{\text{Invisibility potions}}{16}=\frac{1}{2}$

$\frac{\text{Invisibility potions}}{16}\times 16=\frac{1}{2}\times 16$

$\text{Invisibility potions}=8$

Therefore, Lucia can make 8 invisibility potions with 16 eyes of newt.
