Use the plotted point on the following number lines to perform the indicated operation:
\dfrac{3}{5} + \dfrac{19}{5}
- \dfrac{8}{5} + \dfrac{19}{5}
\dfrac{3}{8} - \dfrac{5}{8}
\dfrac{5}{9} - \dfrac{8}{9}
\dfrac{14}{16} - \dfrac{3}{16}
Evaluate:
- \dfrac{7}{3} + \dfrac{17}{3}
- \dfrac{26}{3} + \dfrac{16}{3}
\dfrac{3}{5} - \dfrac{14}{5}
\dfrac{5}{11} + \left( - \dfrac{9}{11} \right)
- \dfrac{5}{9} + \left( - \dfrac{11}{9} \right)

The average water level at a port is marked at 0\text{ m}, and a tide scale is used to measure the water level as it moves up and down with the tide.
When Jack begins his shift at 11 am, the tide scale reads \dfrac{2}{5} \text{ m}. Over the next 7 hours, the tide falls by \dfrac{2}{3}\text{ m}, and his shift ends. State the reading of the tide scale at the end of his shift.
The largest pumpkin in Shawn's farm weighed 3 \dfrac{3}{8} \text{ kg}. This is 1 \dfrac{5}{6} \text{ kg} more than the average weight of pumpkins in his farm. Find the average weight of the pumpkins from Shawn's farm.
Willy and Bill are selling lemonade in the school fair. They have prepared 24 \dfrac{3}{4} cups, which costed them \$18. Each serving of lemonade contains 1 \dfrac{1}{4} cups, which they sell at \$2.
At the end of day, Willy and Bill checked the jug and there is still 3 \dfrac{1}{2} cups left over. How many cups of lemonade did they sell that day?
Diane needs to purchase flour for a cooking class in school. The class is going to prepare a chocolate cake which requires 2 \dfrac{1}{2} \text{ kg} of flour, battered fish which requires 4 \dfrac{3}{4} \text{ kg}of flour, and banana bread which requires 3\dfrac{1}{4} \text{ kg} of flour.
