Question

efetue e simplifique as seguintes frações a)⅔ x⅘. b) ½ x ⁴/⁶ c) 4/4 x 2/5 d) 5/10 x 2/1. e) 2/3 :4/8​

Answer 1

Vamos là.

a) 2/3 * 4/5 = 8/15

b) 1/2 * 4/6 = 4/12 = 1/3

c) 4/4 * 2/5 = 2/5

d) 5/10 * 2/1 = 1

e) (2/3)/(4/8) = (2/3)*(8/4) = 16/12 = 4/3

Answer 2

Explicação passo-a-passo:

$a) \frac{2}{3} \times \frac{4}{5} = \frac{8}{15}$

$b) \frac{1}{2} \times \frac{4}{6} = \frac{4}{12} = \div \frac{4}{4} = \frac{1}{3}$

$c) \frac{4}{4} \times \frac{2}{5} = 1 \times \frac{2}{5} = \frac{2}{5}$

$d) \frac{5}{10} \times \frac{2}{1} = \frac{10}{10} = 1$

$e) \frac{2}{3} \div \frac{4}{8} = \frac{2}{3} \times \frac{8}{4} = \frac{16}{12} = \div \frac{4}{4} = \frac{4}{3}$
