Jenny's math class is learning about fractions. The teacher has placed several partially filled water bottles on her desk. The number of bottles and amount of water each one is filled with is shown below.

Bottles
Fraction of a Liter
How much water will be in each bottle if the total amount of water is equally divided among the bottles?

not sure but it may be b, as i said i'm not sure.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

all of the measures need to be converted to the same measure; such as inches. if you do that it is easy to determine which is the longest, 2500 mm which is approximately 97.5 inches.
