To solve this problem we can use proportion, but first its nice to transform our fraction into improper fraction, so
83 \frac{7}{10}= \frac{837}{10}
and 
2 \frac{1}{4}= \frac{9}{4}
Now we can make proportion

\frac{837}{10}--------------------------\frac{9}{4} of fuel
x-----------------------------1
Now we can cross multiply

x= \frac{ \frac{837}{10} }{ \frac{9}{4} }= \frac{837}{10}* \frac{4}{9} =  \frac{3348}{90}=37.2 - its the result

If r = 2 and s= 7, what is the value of |r| - |s|?
andrew11 [14]

Since r = 2, and s = 7, we would substitute r and s with 2 and 7:

| r | - | s | = | 2 | - | 7 | = 2 - 7 = -5

The answer is -5
