Answer 1

Answer:

$1). \: \frac{3}{4} \times 5 \frac{2}{3} \\ = \frac{3}{4} \times \frac{17}{3} \\ = \frac{17}{4} \\ = 4 \frac{1}{4}$

$2).19 \frac{1}{2} \times \frac{11}{4} \\ = \frac{39}{2} \times \frac{11}{4} \\ = \frac{429}{8} \\ = 53 \frac{5}{8}$

$3). \frac{13}{6} \times \frac{3}{26} \\ = \frac{1}{2} \times \frac{1}{2} \\ = \frac{1}{4}$

$4). \frac{4}{5} \times \frac{12}{7} \\ = \frac{48}{35} \\ = 1\frac{13}{35} </p><p>$

$5). \frac{11}{12} \times \frac{144}{110} \\ = \frac{12}{10} \\ = \frac{6}{5} \\ = 1\frac{1}{5}$

$6).\frac{2}{5} \times 5 \frac{1}{4} \\ = \frac{2}{5} \times \frac{21}{4} \\ = \frac{1}{5} \times \frac{21}{2} \\ = \frac{21}{10} \\ = 2 \frac{1}{10}$

$7).6 \frac{2}{3} \times \frac{9}{5} \\ = \frac{20}{3} \times \frac{9}{5} \\ = \frac{4}{1} \times \frac{3}{1} \\ = 12$

$8).3 \frac{4}{7} \times \frac{3}{5} \\ = \frac{25}{7} \times \frac{3}{5} \\ = \frac{5}{7} \times \frac{3}{1} \\ = \frac{15}{7} \\ = 2 \frac{1}{7}$
