The double number line shows the approximate number of ounces in a certain number of pounds: Two number lines are shown one above the other. The number line on the top shows 3 longer vertical lines. Between each longer vertical line, there is a shorter vertical line. There is 1 shorter vertical line after the last longer vertical line, thereby making a total of 3 shorter vertical lines. The longer vertical lines are labeled 5, 6, and 7. On the right of this number line is written Pounds. The number line below it also has 3 longer vertical lines and 3 shorter vertical lines. The first longer vertical line is ahead of the first longer vertical line of the top number line so that the first shorter vertical line on the lower number line is aligned with the first longer vertical line, labeled 5 on the top number line. The second longer vertical line is ahead of the second longer vertical line of the top number line so that the second shorter vertical line on the lower number line is aligned with the second longer vertical line, labeled 6, on the top number line. The third longer vertical line is ahead of the third longer vertical line of the top number line so that the third shorter vertical line on the lower number line is aligned with the third longer vertical line, labeled 7, on the top number line. The longer vertical lines on the bottom number line are labeled 72, 88, and 104 respectively. On the right of this number line is written Ounces.
