What is 2 and 3 fifths - 1 and 6 sevenths?

Answer 1

To subtract the mixed numbers (2 \frac{3}{5}) and (1 \frac{6}{7}), first convert them to improper fractions. This gives us (\frac{13}{5}) and (\frac{13}{7}). To perform the subtraction, find a common denominator, which is 35. The fractions become (\frac{91}{35}) and (\frac{65}{35}). Subtracting these yields (\frac{26}{35}), so (2 \frac{3}{5} - 1 \frac{6}{7} = \frac{26}{35}).
