Answer:

66 2/3 %

Step-by-step explanation:

First find the students not in the 8th grade

24 - 8 = 16

16 students are not in the 8th grade

Take the fraction of the students not in the 8th grade over the total

16/24 = 2/3

Change to a decimal

.66666666666

Multiply by 100 to change to a percent

66.666666%

66 2/3 %

$\huge\text{Hey there!}$

$\huge\text{The word \bf{product}}\huge\text{ means multiply in}\\\huge\text{mathematics.}$

$\huge\text{The number is unknown so we can label}\\\huge\text{it as: x}$

$\huge\text{Your equation will be setup like this: -2.5x = 60}$

$\text{-2.5x = 60}\\\text{First divide both sides by -2.5}\rightarrow\dfrac{-2.5\text{x}}{-2.5} = \dfrac{60}{-2.5}\\\text{Cancel out:}\dfrac{2.5\text{x}}{2.5}\text{ because it equals 1}\\\\\text{Keep:}\dfrac{60}{-2.5}\text{because it helps us find the unknown number}\\\\\\\boxed{\boxed{\text{Answer: x = -24}}}\checkmark$
