Question

me ajudem rapido por favor

Answer 1

a)

$2 \times \frac{5}{4} \times 3 \times \frac{1}{6 } = \\ \frac{2 \times 5 \times 3 \times 1}{4 \times 1 \times 1 \times 6} = \\ \frac{30}{24 } = \frac{10}{8} = \frac{5}{4}$

b)

$\frac{2}{12} \times \frac{6}{11} \times \frac{33}{2} = \frac{6 \times 33}{21 \times 11} = \frac{198 \div 33}{132 \div 33} = \frac{6 \div 2}{4 \div 2} = \frac{3}{2}$

espero que isso ajude vc
