9. Hana asked her classmates which fruit they like best. She wrote down the results: apples = 15, bananas = 11, grapes = 18. Draw a bar graph to show how many classmates chose each fruit. Answer: A bar graph with bars at apples=15, bananas=11, grapes=18 Solution: Draw a vertical line on the left side of your paper. Mark numbers from 0 to 20 going up, with each space equal. Draw a horizontal line at the bottom.
   Full step-by-step solution

   Step 1: Draw a vertical line on the left side of your paper. This is the number line. Mark numbers from 0 to 20 going up, with each space equal. Step 2: Draw a horizontal line at the bottom. This is where you will write the fruit names. Step 3: For apples, draw a bar that reaches up to the number 15. Color it in. Step 4: For bananas, draw a bar next to the apple bar that reaches up to the number 11. Color it in. Step 5: For grapes, draw a bar next to the banana bar that reaches up to the number 18. Color it in. Step 6: Label each bar with the fruit name underneath. The tallest bar is grapes (18), then apples (15), then bananas (11). This is your bar graph.
