Question

1- Passe para a forma mista as seguintes fraçõos impróprias:
$a) \: \frac{26}{5} \: \: b) \: \frac{147}{13} \: \: c) \: \frac{125}{8} \: \: d) \: \frac{59}{2} \:$
$e) \: \frac{47}{6} \: f) \: \frac{1.313}{25}$

2- Transforme as frações mistas em frações impróprias,

$a) \: 2 \: \frac{1}{3} \: \: b) \: 1 \frac{1}{3} \: \: c) \frac{2}{7} \: d) \: 2 \frac{3}{5}$
$e) \: 4 \frac{2}{7} \: f) \: 3 \frac{5}{11}$

SENÃO IREI DENUNCIAR!! ;) ​

Answer 1

Explicação passo-a-passo:

1)

a)

$\sf \dfrac{26}{5}=\dfrac{25}{5}+\dfrac{1}{5}=\red{5~\dfrac{1}{5}}$

b)

$\sf \dfrac{147}{13}=\dfrac{143}{13}+\dfrac{4}{13}=\red{11~\dfrac{4}{13}}$

c)

$\sf \dfrac{125}{8}=\dfrac{120}{8}+\dfrac{5}{8}=\red{15~\dfrac{5}{8}}$

d)

$\sf \dfrac{59}{2}=\dfrac{58}{2}+\dfrac{1}{2}=\red{29~\dfrac{1}{2}}$

e)

$\sf \dfrac{47}{6}=\dfrac{42}{6}+\dfrac{5}{6}=\red{7~\dfrac{5}{6}}$

f)

$\sf \dfrac{1313}{25}=\dfrac{1300}{25}+\dfrac{13}{25}=\red{52~\dfrac{13}{25}}$

2)

a)

$\sf 2~\dfrac{1}{3}=\dfrac{2\cdot3+1}{3}=\dfrac{6+1}{3}=\red{\dfrac{7}{3}}$

b)

$\sf 1~\dfrac{1}{3}=\dfrac{1\cdot3+1}{3}=\dfrac{3+1}{3}=\red{\dfrac{4}{3}}$

c)

$\sf 2~\dfrac{2}{7}=\dfrac{2\cdot7+2}{7}=\dfrac{14+2}{7}=\red{\dfrac{16}{7}}$

d)

$\sf 2~\dfrac{3}{5}=\dfrac{2\cdot5+3}{5}=\dfrac{10+3}{5}=\red{\dfrac{13}{5}}$

e)

$\sf 4~\dfrac{2}{7}=\dfrac{4\cdot7+2}{7}=\dfrac{28+2}{7}=\red{\dfrac{30}{7}}$

f)

$\sf 3~\dfrac{5}{11}=\dfrac{3\cdot11+5}{11}=\dfrac{33+5}{11}=\red{\dfrac{38}{11}}$
