Do they know how to divide?

If so, tell them to divide the number in as many ways until you go past the number

For example, if your seeing if 9 is a prime number divide 9 by ,1,2,3,4,5,6,7,8,9 and only count the whole numbers.

This sounds complicated so just teach them simple time tables

If y varies inversely as x find the constant of variation and that inverse of variation

True [87]

$\bf \begin{array}{llllll}
\textit{something}&&\textit{varies inversely to}&\textit{something else}\\ \quad \\
\textit{something}&=&\cfrac{{{\textit{some value}}}}{}&\cfrac{}{\textit{something else}}\\ \quad \\
y&=&\cfrac{{{\textit{k}}}}{}&\cfrac{}{x}
\\
&&y=\cfrac{{{ k}}}{x}
\end{array}\\\\
-----------------------------\\\\
\textit{now, we know that }
\begin{cases}
y=120\\
x=7
\end{cases}\implies 120=\cfrac{k}{7}$

solve for "k", to find "k" or "constant of variation"
