d)1+3/5-1/6-1/2=
Urgenteeeeeeeeee​

Answer 1

Resposta:

a)4 + 1/2+2/3=

$4 + 1/2+2/3= \frac{12 + 3 + 4}{3} = \frac{19}{3}$

b)2- 1/3-1/5=

$2- 1/3-1/5= \frac{30 - 5 - 3}{15} = \frac{22}{15}$

c)1/3+ 2 1/5

$1/3+ 2 1/5 = \frac{5 + 63}{15} = \frac{68}{15}$

d)1+3/5-1/6-1/2=

$1+3/5-1/6-1/2= \frac{30 + 18 - 5 - 15}{30} = \frac{28}{30} = \frac{14}{15}$

espero que isso ajude vc

Answer 2

Resposta:

$a) \: \frac{31}{6} \\ b) \: \frac{22}{15} \\ c) \: \frac{38}{15} \\ d) \: \frac{14}{15}$

Explicação:

$a) \: 4 + \frac{1}{2} + \frac{2}{3} = \frac{24 + 3 + 4}{6} = \frac{31}{6}$

$b) \: 2 - \frac{1}{3} - \frac{1}{5} = \frac{30 - 5 - 3}{15} = \frac{22}{15}$

$c) \: \frac{1}{3} + 2 \frac{1}{5} = \frac{1}{3} + \frac{11}{5} = \frac{5 + 33}{15} = \frac{38}{15}$

$d) \: 1 + \frac{3}{5} - \frac{1}{6} - \frac{1}{2} = \frac{30 + 18- 5 - 15}{30} = \frac{28}{30} = \frac{14}{15}$
