Answer 1

Resposta:

a)

$2 \div 5 - 3 + 11 \div 2 = \frac{29}{10}$

b)

$1 - 3 \div 4 + 1 \div 6 = \frac{1}{12}$

c)

$(4 - 3/2) - (- 1/2 - 4/3) = \frac{13}{3}$

d)

$12/5 + 2 - 0,1=4.3$

e)

$(+3/5) . ( -1/3)= \frac{3}{5} \frac{ - 1}{3}$

f)

$(- 1/2) . (2/3) . (- 3/7)= \frac{ - 1}{2 \frac{2}{3 \frac{ - 3}{7} } }$

g)

$(-1) . (5/3) . (3/5) . (1/2)={ - 1 {3}{5}$
