Distance of bird from sea level= #137/10# =13.7 ft. And,

Distance of fish from sea level= # 162/10 # = 16.2 ft.

Hence, the fish is farthest from sea level.

Explanation:

Given that:
A bird flies 13 7/10 feet above sea level. = #13 7/10# ft.

A fish swims 16 1/5 feet below sea level. =#16 1/5# ft.

To find: Which is farthest from sea level.

We convert the mixed fractions into improper fractions and then compare:

The bird flies above sea level. = #13 7/10# ft.

= #(13\times 10 +7)/10# ft.

Distance of bird from sea level= #137/10# ft.
and

The fish swims below sea level. =#16 1/5# ft.

= #(16\times 5 +1)/5# ft.

Distance of fish from sea level= # 81/5# ft. ----equation (2)

To compare the two quantities, their denominators must be same , so we will multiply and divide equation (2) by 2:

Distance of fish from sea level= # 81/5 (2/2)# ft. = #162/ 10# ft.

Now comparing#137/10 #and #162/10#, we find that , as the larger fraction is one with grater numerator,

#162/10 > 137/10#.

Hence, the fish is farthest from the sea level.

The fish is further from sea level.

Explanation:

You only need to look at the whole numbers to compare the distances from sea level.

#16 >13# therefore the fraction involving #16# is further from sea level than the fraction with #13#
