Question

02-Calcule as multiplicações e divisoes de frações.
a) 5/8 x 1/6
b) 3/5 x 34
c) 2/3 : 5/6
d) 4/5: 2/3​

Answer 1

$a) \frac{5}{8} \times \frac{1}{6} = \frac{5 \times 1}{8 \times 6} = \frac{5}{48}$

$b) \frac{3}{5} \times 34 = \frac{3}{5} \times \frac{34}{1} = \frac{3 \times 34}{5 \times 1} = \frac{102}{5}$

$c) \frac{2}{3} \div \frac{5}{6} = \frac{2}{3} \times \frac{6}{5} = 2 \times \frac{2}{5} = \frac{4}{5}$

$d)\frac{4}{5 } \div \frac{2}{3} = \frac{4}{5} \times \frac{3}{2} = \frac{2}{5} \times 3 = \frac{6}{5}$
