Question

1)efetue e simplefique.


a) 1/3:1/4=

b) 5/6:2/15=

c) 16/5:8/10=​

Answer 1

a)

$\frac{1}{3} \div \frac{1}{4} = \frac{1}{3} \times 4 = \frac{4}{3}$

b)

$\frac{5}{6} \div \frac{2}{15} \\ \frac{5}{6} \times \frac{15}{2} = \frac{75 \div 3}{12 \div 3} = \frac{25}{4}$

c)

$\frac{16}{5} \div \frac{8}{10} = \frac{16}{5} \times \frac{10}{8} = \frac{160}{40} = 4$

Answer 2

Resposta:

Explicação passo-a-passo:

a) 1/3 x 4/1 =   4/3  

b) 5/6 x  15/2 =  75/12  divide por 3 os dois e teremos = 25/4

c) 16/5 x 10/8 =  160/40   divide por 40 os dois e teremos = 4
