Question

me ademmm pvv eu pci dela rapido pvvv ​

Answer 1

Explicação passo-a-passo:

3) a)

$\frac{2 + 5}{9} = \frac{7}{9}$

b)

$\frac{4 + 2}{10} = \frac{6}{10} = \frac{3}{5}$

c)

$\frac{2 + 3}{15} = \frac{5}{15} = \frac{1}{3}$

d)

$\frac{5 + 3 + 1}{12} = \frac{9}{12} = \frac{3}{4}$

e)

$\frac{5 + 3}{4} = \frac{8}{4} = 2$

f)

$\frac{1 + 2 - 3}{6} = \frac{0}{6} = 0$

isso sse for -3/6

4) a)

$\frac{8 - 2}{9} = \frac{6}{9} = \frac{2}{3}$

b)

$\frac{7 - 1}{5} = \frac{6}{5}$

c)

$\frac{15 - 9}{8} = \frac{6}{8} = \frac{3}{4}$

d)

$\frac{ 9- 4}{5} = \frac{5}{5} = 1$

e)

$\frac{3 - 3}{7} = \frac{0}{7} = 0$

f)

$\frac{11 - 3}{12} = \frac{8}{12} = \frac{2}{3}$
