Question

2/3+1/9
3/4:7/8
3-2/3*3/7

Answer 1

$\frac{2}{3} + \frac{1}{9} = \frac{6}{9} + \frac{1}{9} = \frac{7}{9}$

$\frac{3}{4} \div \frac{7}{8} = \frac{3}{4} \times \frac{8}{7} = \frac{6}{7}$

$3 - \frac{2}{3} \times \frac{3}{7} = 3 - \frac{2}{7} = \frac{21}{7} - \frac{2}{7} = \frac{19}{7} = 2 \frac{5}{7}$
