1 3/4 * 2 1/7 = 3 3/4

Answer 2

$1) \frac{17}{36} \times \frac{9}{34} = \frac{1}{8}$

$4) \frac{9}{16} \div \frac{21}{24} = \frac{9}{16} \times \frac{24}{21} = \frac{3}{6}$

$2)2 \frac{7}{16} \div 8 = \frac{39}{16} \times \frac{1}{8} = \frac{39}{128}$

$5)2 \frac{1}{3} \div 21 = \frac{7}{3} \times \frac{1}{21} = \frac{1}{9}$

$3)1 \frac{3}{4} \times 2 \frac{1}{7} = \frac{7}{4} \times \frac{15}{7} = \frac{15}{4} = 3 \frac{3}{4}$

$6)1 \frac{2}{3} \div 3 \frac{5}{6} = \frac{5}{3} \times \frac{6}{23} = \frac{10}{23}$
