15•42/51•2/7

alguém me ajuda rápido pffff,é p amanhã ​​

Answer 1

$\mathsf{\dfrac{2}{9}. \dfrac{11}{5}. \dfrac{3}{14} = \dfrac{66 \div 3}{630 \div 3} = \dfrac{22}{210}}$

$\mathsf{\dfrac{21}{16}. \dfrac{3}{7}.12 = \dfrac{756 \div 28}{112 \div 28} = \dfrac{27}{4}}$

$\mathsf{15. \dfrac{42}{51}. \dfrac{2}{7} = \dfrac{1260 \div 21}{357 \div 21} = \dfrac{60}{17}}$
