Question

calcule a soma das fraçoes a)1/2 + 4/2 b)2/3 + 7/3 c)1/2 + 4/5 d)5/6 + 1/2​

Answer 1

Resposta:

Calcule a soma das frações:

a)1/2 + 4/2 b)2/3 + 7/3 c)1/2 + 4/5 d)5/6 + 1/2​

a)  2,5

b) 3

c) 1,3

d) 1,3

a)

$1/2+4/2= 1/2+2 = 5/25/2=2 Resto 1\\5/2= 2 1/2=2 1/2 Simplificando= 2,5$

B)

$=\frac{2}{3}+7/3 =\frac{2}{3}+\frac{7}{3} =3$

C)

$=\frac{1}{2}+4/5=\frac{1}{2}+\frac{4}{5}=\frac{13}{10} =1\frac{3}{10}Simplificando= 1,3$

d)

$=\frac{5}{6}+1/2 =\frac{4}{3} =1\frac{1}{3}Simplifica= 1,3$
