An estar escrito en la forma n / 1. Por ejemplo, 5 = 5/1 y, por tanto, 5 es un número racional. Sin embargo, números como 1/2, 45454737/2424242 y -3/7 también son racionales, ya que son fracciones cuyo numerador y denominador son números enteros.

Answer:
1.5 cm/s
Step-by-step explanation:
The graph shows the speed of a worm as a relationship between the distance it can travel in centimeters over time, or seconds. Since the graph forms a straight line, then we know that the speed of the worm is constant over time, meaning that he will move the same distance each second. Given the point (6,9) on the graph, this tells us that the worm moved 9 centimeters in 6 seconds or:

So, the ratio of centimeters over seconds is 9/6. However, unit rate is the distance every second or putting the ratio over '1'. We can do this by diving the numerator by the denominator or 9 ÷ 6 = 1.5 centimers/second.
To find the percent of the total that George collected, you need to create a ratio with the number of pounds George collected compared to the number of total pounds that were collected.
You will then divide these to find the part (decimal) that George collected. You can convert the decimal to a percent.
3 1/4+6 1/3+11 1/6 = 20 3/4 total pounds of cans.
11 1/6 George
20 3/4 total
11 1/6÷20 3/4 = 0.538
0.538 is approximately 54%.
George collected proximately 54% of the total amount of cans.
