Question

the whole 5th grade is starting new reading log competition. mr. Marsh is planning to buy each scholar in the winning advisory a prize. if he can spend $75 on one-sixth of the winning advisory how much can he spend on the whole advisory?

Answer 1

If Mr. Marsh can spend $75 on one-sixth, it menas that $75 is equal to 1/6 of the advisory.

$75\Rightarrow\frac{1}{6}$

if we want to know the whole, it can be represented as a 1.

$\begin{gathered} 75\Rightarrow\frac{1}{6} \\ x\Rightarrow1 \end{gathered}$

solve the relationship

$\begin{gathered} x=\frac{1\cdot75}{\frac{1}{6}} \\ x=(1\cdot75)\cdot6 \\ x=450 \end{gathered}$

According to this Mr. Marsh can spend $450 on the whole advisory.
