Question

Reduza ao menor denominador comum as frações abaixo:

a) 1/2 , 3/4 =

b) 2/3 , 3/4 , 2/5=

c) 3/4 , 1/5 , 1/6 =

d) 4/5 , 1/6 , 3/8 =

e) 1/2 , 1/4 , 3/10 =

​

Answer 1

Resposta:

Reduzindo os termos semelhantes temos :

a) 1/2 , 3/4 =            MMC  =  2/4,          3/4

b) 2/3 , 3/4 , 2/5=   MMC =  40/60,    45/60,    24/60

c) 3/4 , 1/5 , 1/6 =   MMC =  45/60,     12/60,       10/60

d) 4/5 , 1/6 , 3/8 =  MMC =  96/120,   20/120,    45/120  

e) 1/2 , 1/4 , 3/10 =   MMC =  10/20,     5/20,       6/20

Answer 2

Explicação passo-a-passo:

$a) \frac{1}{2} \: e \: \frac{3}{4} = mmc = 4$

$\frac{2}{4} \: \: e \: \: \frac{3}{4}$

$b) \frac{2}{3} \: \: \frac{3}{4} \: e \: \frac{2}{5} = \: \: \: 60$

$\frac{40}{60} \: \: \: \frac{45}{60} \: \: e \: \: \frac{24}{60}$

$c) \frac{3}{4} \: \: \frac{1}{5} \: \: \: \frac{1}{6} = mmc = 120$

$\frac{90}{120} \: \: \: \frac{24}{120} \: \: \: \frac{20}{120}$

$d) \frac{4}{5} \: \: \frac{1}{6} \: \: e \: \: \frac{3}{8} = mmc = 240$

$\frac{192}{240} \: \: \frac{40}{240} \: \: e \: \: \frac{90}{240}$

$e) \frac{1}{2} \: \: \frac{1}{4} \: \: \: \frac{3}{10} = mmc = 20$

$\frac{10}{20} \: \: \frac{5}{20} \: \: e \: \: \frac{6}{20}$
