Question

At a school 40%of six grade students said hop hop is there favorite kind of music. If 100 six grade students perfer hip hop music, how many six graders are at the school?

Answer 1

if in the school there are 100 students prefer Hip Hop then we have to calculate the 100% with a rule of three so:

`\begin{gathered} x\to100 \\ 100\to40 \end{gathered}`

so the equation is:

`\begin{gathered} x=(100\cdot100)/(40) \\ x=250 \end{gathered}`

So in total there are 250 students
