Answer 2

Explicação passo-a-passo:

${3\over7}\times{5\over2}={3.5\over7.2}={15\over14}\\ \\ {\not^14\over\not_15}\times{\not10^2\over3}\times{7\over\not12_3}=~~~~ pode~~simplificar~~{10\over5}~~e~~~{4\over12}\\ \\ {1\over1}\times{2\over3}\times{7\over3}={14\over9}\\ ---------------\\ {8\over3}\div{6\over5}=\\ \\ {8\over3}\times{5\over6}={40\over18}~~simplificando~~{40:2\over18:2}={20\over9}$
