Well you could round it to the 4th decimal, which would be 2.7183
That as a mixed number would be
At around 20'000ft. and higher.
1 whole and 1/4 substracted to 1/3 can be written as:
1 1/4 - 1/3 =
= 5/4 - 1/3
We have to find a common denominator which is 12:
5/4 = 15/12
1/3 = 4/12
So now we just substract numerators:
15/12 - 4/12 = <u>11/12</u>
Simple.
Divide 50 by each side.
