Determine the number of fractions in the pattern below that are expressed in lowest terms.
\(\frac{1}{2019},\frac{2}{2018},\frac{3}{2017},\dots\frac{1010}{1010}\)
Any explanation would be helpful!
Note that in every term, the numerator increases by 1, and the denominator decreases by 1.
Because the first term starts in 1 and increases by 1, the number of terms is the last term.
Can you take it from here?
