Lucia is making invisibility potions. Each potion requires 2 eyes of newt. How many invisibility potions can Lucia make with 16 eyes of newt?

8.

16 eyes total / 2 eyes per potion = 8 potions

8 invisibility potions

Step-by-step explanation:

2 eyes of a newt is required to make 1 invisibility portion

Therefore,

2 eyes of newt = 1 invisibility potion

16 eyes of newt = x invisibility potions

We would cross multiply

2x = 16

x = 16 : 2

x = 8 invisibility portions.

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