Question

out of the 25 students in Mrs. Green's class, 19 have a pet. What percent of the students have a pet?

Answer 1

To find the percent we can use the rule of three:

`\begin{gathered} 25\rightarrow100 \\ 19\rightarrow x \end{gathered}`

then:

`\begin{gathered} x=(19\cdot100)/(25) \\ x=76 \end{gathered}`

Therefore 76% of students have pets.
