- Ratios Troy and David were selling water bottles to raise money for new football uniforms. Troy sold 9 water bottles for every 5 water bottles David sold. Togethe they sold 280 water bottles. a) Draw a bar model to represent the situation.

1) \( \left[\begin{array}{l}3 \\ 4\end{array}\right]-\left[\begin{array}{l}-5 \\ -1\end{array}\right] \)

c) \( 3,23-3,23= \)

b) \( -5: \frac{10}{3}+\frac{10}{4} \)

Convince Me! Use Structure Dario says, "I can find \( 9 \times 0<3 \times 1 \) without computing. I can think about properties that I know." What could he mean?
