Question

Find the fraction of the total items to be filled with sprinklers.

• A. $\frac{3}{1}$
• B. $\frac{4}{1}$
• C. $\frac{2}{1}$

Answer 1

$\frac{1}{1}$ + $\frac{1}{1}$ + $\frac{1}{1}$ + $\frac{1}{1}$ = $\frac{4}{1}$



$\frac{1}{1}$ + $\frac{1}{1}$ = $\frac{2}{1}$



$\frac{1}{1}$ + $\frac{1}{1}$ + $\frac{1}{1}$ = $\frac{3}{1}$
