Answer:
2 1/2
Step-by-step explanation:
1st, convert the fractions
2 2/3 = 2 4/6 = 16/6
5 1/6 = 31/6
31/6-16/6 = 15/6 = 2 3/6 = 2 1/2
Arranging units from smallest to largest:
pm, nm, um, mm, cm, dm, m, km.
Individual measurements in terms of 1 meter.
1 x 10^12 pm = 1 m
1 x 10^9 nm = 1m
1 x 10^6 um = 1m
1 x 10^3 mm = 1m
1 x 10^2 cm = 1m
1 x 10^1 dm = 1m
1m = 1m
1 x 10^-3 km <span> = 1m</span>

Answer:
the answer is B
Step-by-step explanation:
Ok, so I'll make an example problem to show.
There's a forest in town and it's recorded that there are 5 bears and 100 squirrels in it.
First, you would make this a ratio so that would be 5:100. 5 being the bears and 100 being the squirrels.
To simplify it, just make it into a fraction. The first number, going from left to right, would be the numerator and 100 would be the denominator.
5
-----
100
To simplify, just divide by the greatest common factor which would be 5 in this case.
5 1
----- / 5 = ----
100 20
