Efetue os cálculos algébricos a seguir:

Answer 1

Ola!

$a) \\\frac{-5}{8}+\frac{5}{6} \\\\\frac{-15}{24} +\frac{20}{24} \\\\\frac{-15+20}{24}=\frac{5}{24}$

$b)\\3,75-4\\-4-3,75= -0,25$

$c)\\\frac{-1}{12} +\frac{3}{10}\\\\\frac{5}{60} + \frac{18}{60}\\\\\frac{-5+18}{60} = \frac{13}{60}$

$d)\\-0,64-0,28=-0,92$

$e)\\6,75+9,45=16,20$

$f)\\\frac{5}{6} +\frac{3}{4} \\\\\\frac{-10}{12} +\frac{9}{12} \\\\\frac{-10+9}{12} =\frac{-1}{12}$

$g) \\11,05-13\\\-3-11,05=-1,95$

$h)\\-2,91+3,07=+0,16$
