Answer to A Practical Example


Lunga has taken longer, because his first decimal place (2) is bigger than the 1 that applies to Johannes. 

Lunga has taken 37\(\frac{2}{10}\) minutes and Johannes has taken 37\(\frac{1}{10}\) \(\frac{5}{100}\) + \(\frac{9}{1000}\), and Johannes’ time is less than Lunga’s.

The 5 and 9 count for less because they are smaller fractions (2nd and 3rd decimal).
