Answer 1

Resposta:

a)

$2\dfrac{1}{2} = \dfrac{2.2+1}{2} = \dfrac{5}{2}$

b)

$2 = \dfrac{2}{1}$

c)

$5\dfrac{2}{5} = \dfrac{5.5+2}{5} = \dfrac{27}{2}$

d)

$1\dfrac{3}{4} = \dfrac{4.1+3}{4} = \dfrac{7}{2}$

e)

$7\dfrac{1}{10} = \dfrac{10.7+1}{10} = \dfrac{71}{10}$

f)

$12\dfrac{3}{8} = \dfrac{12.8+3}{8} = \dfrac{99}{8}$

Answer 2

Resposta:

Explicação passo-a-passo:

$\boxed{2 \frac{1}{2} = \frac{4 + 1}{2} = \frac{5}{2} }$

$\boxed{2 = \frac{2}{1} }$

$\boxed{5 \frac{2}{5} = \frac{25 + 2}{5} = \frac{27}{5} }$

$\boxed{1 \frac{3}{4} = \frac{4 + 3}{4} = \frac{7}{4}}$

$\boxed{7 \frac{1}{10} = \frac{70 + 1}{10} = \frac{71}{10}}$

$\boxed{12 \frac{3}{8} = \frac{96 + 3}{8} = \frac{99}{8}}$
