Answer 2

Answer:

Solution :-

$1) \dfrac{84}{11} \times \dfrac{22}{12}$

$\implies\dfrac{\: \: \: \: \: \cancel{1848}^{\: 14}}{\: \cancel{132}^{\: 1}}$

$\implies 14$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: 14$

$2) \dfrac{1}{5} \times \dfrac{35}{4}$

$\implies\dfrac{\: \: \: \: \: \cancel{35}^{\:7}}{\: \cancel{20}^{\: 4}}$

$\implies\dfrac{7}{4}$

$\implies\ 1.75$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: 1.75$

$3) \dfrac{2}{12} \times \dfrac{1}{8}$

$\implies\dfrac{\: \: \: \: \: \cancel{2}^{\:1}} {\: \cancel{96}^{\: 48}}$

$\implies\dfrac{1}{48}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: \dfrac{1}{48}$

$4) \dfrac{65}{10} \times \dfrac{20}{13}$

$\implies\dfrac{\: \: \: \: \: \cancel{1300}^{\: 10}}{\: \cancel{130}^{\: 1}}$

$\implies 10$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: 10$

$5) \dfrac{12}{12} \times \dfrac{1}{8}$

$\implies\dfrac{\: \: \: \: \: \cancel{12}^{\: 1}}{\: \cancel{96}^{\: 8}}$

$\implies\dfrac{1}{8}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: \dfrac{1}{8}$

$6) \dfrac{24}{6} \times \dfrac{2}{12}$

$\implies\dfrac{\: \: \: \: \: \cancel{48}^{\: 2}}{\: \cancel{72}^{\: 3}}$

$\implies\dfrac{2}{3}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: \dfrac{2}{3}$

$7) \dfrac{20}{5} \times \dfrac{15}{25}$

$\implies\dfrac{\: \: \: \: \: \cancel {300}^{\: 12}}{\: \cancel{125}^{\: 5}}$

$\implies\dfrac{12}{5}$

$\implies 2.4$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: 2.4$

$8) \dfrac{3}{4} \times \dfrac{8}{12}$

$\implies\dfrac{\: \: \: \: \: \: \cancel{24}^{\: 1}}{\: \cancel{48}^{\: 2}}$

$\implies\dfrac{1}{2}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: \dfrac{1}{2}$

$9) \dfrac{36}{48} \times \dfrac{2}{6}$

$\implies\dfrac{\: \: \: \: \: \cancel{72}^{\:1}}{\: \cancel{288}^{\: 4}}$

$\implies\dfrac{1}{4}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: \dfrac{1}{4}$

$10) \dfrac{17}{12} \times \dfrac{52}{68}$

$\implies\dfrac{\: \: \: \: \: \cancel{884}^{\: 13}}{\: \cancel{816}^{\: 12}}$

$\implies\dfrac{13}{12}$

$\implies 1.083$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: 1.083$

$11) \dfrac{2}{26} \times \dfrac{13}{42}$

$\implies\dfrac{\: \: \: \: \: \cancel{26}^{\: 1}} {\: \cancel{1092}^{\: 42}}$

$\implies\dfrac{1}{42}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: \dfrac{1}{42}$

$12) \dfrac{30}{14} \times \dfrac{28}{60}$

$\implies\dfrac{\: \: \: \: \: \cancel{840}^{\: 1}}{\: \cancel{840}^{\: 1}}$

$\implies 1$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: 1$

$13) \dfrac{40}{10} \times \dfrac{7}{20} \times \dfrac{1}{7}$

$\implies\dfrac{\: \: \: \: \: \cancel{280}^{1}}{\: \cancel{1400}^{5}}$

$\implies\dfrac{1}{5}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\:\dfrac{1}{5}$

$14) \dfrac{8}{10} \times \dfrac{3}{12} \times \dfrac{24}{9}$

$\implies\dfrac{\: \: \: \: \: \cancel{576}^{\: 8}}{\: \cancel{1080}^{\: 15}}$

$\implies\dfrac{8}{15}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: \dfrac{8}{15}$

$15) \dfrac{5}{8} \times \dfrac{12}{15} \times \dfrac{9}{5}$

$\implies\dfrac{\: \: \: \: \: \cancel{540}^{\: 9}}{\: \cancel{600}^{\: 10}}$

$\implies\dfrac{9}{10}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: \dfrac{9}{10}$

$16) 5\dfrac{3}{9} \times 7\dfrac{3}{6}$

$\implies\dfrac{48}{9} \times \dfrac{45}{6}$

$\implies\dfrac{\: \: \: \: \: \cancel{2160}^{\: 40}}{\: \cancel{54}^{\: 1}}$

$\implies 40$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: 40$

$17) 4\dfrac{4}{7} \times 2\dfrac{5}{8}$

$\implies\dfrac{32}{7} \times \dfrac{21}{8}$

$\implies\dfrac{\: \: \: \: \: \cancel{672}^{\: 12}}{\: \cancel{56}^{\: 1}}$

$\implies 12$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: 12$

$18) \dfrac{1}{48} \times \dfrac{96}{12} \times 6$

$\implies\dfrac{\: \: \: \: \: \cancel{576}^{\: 1}}{\: \cancel{576}^{\: 1}}$

$\implies 1$
