What fraction is exactly between 1/3 and 1/7?


To find the fraction that is exactly between 1/3 and 1/7, we can take the average of the two fractions.


The average of two fractions \( \frac{a}{b} \) and \( \frac{c}{d} \) is given by:


\[ \frac{a}{b} + \frac{c}{d} \div 2 \]


In this case, the fractions are 1/3 and 1/7.


So, the average fraction is:


\[ \frac{1}{3} + \frac{1}{7} \div 2 \]


To add these fractions, we need to find a common denominator, which is the least common multiple (LCM) of 3 and 7, which is 21.


So, the fractions become:
