Answer 1

Explicação passo-a-passo:

a) $\sf 2~\dfrac{7}{9}=\dfrac{2\cdot9+7}{9}=\dfrac{18+7}{9}=\red{\dfrac{25}{9}}$

b) $\sf 3~\dfrac{1}{2}=\dfrac{3\cdot2+1}{2}=\dfrac{6+1}{2}=\red{\dfrac{7}{2}}$

c) $\sf 5~\dfrac{7}{13}=\dfrac{5\cdot13+7}{13}=\dfrac{65+7}{13}=\red{\dfrac{72}{13}}$

d) $\sf 1~\dfrac{1}{8}=\dfrac{1\cdot8+1}{8}=\dfrac{8+1}{8}=\red{\dfrac{9}{8}}$

e) $\sf 12~\dfrac{3}{4}=\dfrac{12\cdot4+3}{4}=\dfrac{48+3}{4}=\red{\dfrac{51}{4}}$
