Final answer:
To compare the lengths of the baguettes, convert all the measurements to a consistent unit. The third baguette is the longest at 94.2 centimeters and the first baguette is the shortest at 84 centimeters.
Step-by-step explanation:
To compare the lengths of the baguettes, we need to convert all the measurements to a consistent unit. Since 1 meter is equal to 100 centimeters and 1 meter is also equal to 1000 millimeters, we can convert the second baguette to centimeters by multiplying 0.9 by 100 to get 90 centimeters. We can also convert the third baguette to centimeters by multiplying 942 by 0.1 to get 94.2 centimeters.
Now that we have all the measurements in centimeters, we can see that the third baguette is the longest at 94.2 centimeters. The first baguette is the shortest at 84 centimeters.
