18/11 - 4/11

1/4 + 1/2

2/8 + 1/4

POR FAVOR GENTE ME AJUDAA

Answer 1

Resposta:

3/2 , 2/3, 14/11, 3/4 , 1/2

Explicação passo-a-passo:

$\frac{1}{4} + \frac{5}{4}$

$\frac{4 + 20}{16} \\ \\ \frac{24}{16} ^{ \div 8} = \frac{3}{2}$

$\frac{7}{9} - \frac{1}{9} \\ \\ \frac{63 - 9}{81} \\ \\ \frac{54} {81} ^{ \div 9} = \frac{6}{9} ^{ \div 3} = \frac{2}{3}$

$\frac{18}{11} - \frac{4}{11} \\ \\ \frac{154}{121} ^{ \div 11} = \frac{14}{11}$

$\frac{1}{4} + \frac{1}{2} \\ \\ \frac{6}{8} ^{ \div 2} = \frac{3}{4}$

$\frac{2}{8} + \frac{1}{4} \\ \\ \frac{16}{32}^{ \div 16} = \frac{1}{2}$

Answer 2

Resposta:

A)

$\frac{1}{4} + \frac{5}{4} \\ \\ \frac{ 6}{4} \div 2 \\ \\ \frac{ 3}{2}$

B)

$\frac{7}{9} - \frac{1}{9} \\ \\ \frac{6}{9} \div 3 \\ \\ \frac{2}{3}$

C)

$\frac{18}{11} - \frac{4}{11} \\ \\ \frac{14}{11}$

D)

$\frac{1}{4} + \frac{1}{2} \\ \\ \frac{2 + 4}{8} \\ \\ \frac{6}{8} \div 2 \\ \\ \frac{3}{4}$

E)

$\frac{2}{8} + \frac{1}{4} \\ \\ (\frac{2}{8} \div 2 )+ \frac{1}{4} \\ \\ \frac{1}{4} + \frac{1}{4} \\ \\ \frac{2}{4} \div 2 \\ \\ \frac{1}{2}$
