Answer 2

Answer:

$\large{ \bold{1\frac{9}{35} }}$

Step-by-step explanation:

$3 \frac{2}{5} - 2 \frac{1}{7} \\ \\ = \frac{5(3) + 2}{5} - ( \frac{7(2) + 1}{7} ) \\ \\ = \frac{17}{5} - \frac{15}{7} \\ \\ = \frac{17(7) - 15(5)}{35} \\ \\ = \frac{119 - 75}{35} \\ \\ = \frac{44}{35} \\ \\ = \frac{35 + 9}{35} \\ \\ = 1 \frac{9}{35}$
