Answer 1

Resposta:

Explicação passo a passo:

a) 3/14+2/7+1 = ?   $\frac{3}{14} +\frac{2}{7} +1 =\frac{3}{2} =1,5$

b) 2+3/5+7/15= ?   $2+\frac{3}{5} +\frac{7}{15} =\frac{46}{15} =3,06$

c) 1/4-2/10= ?  $\frac{1}{4} -\frac{2}{10} =\frac{1}{20} =0,05$

d) 7/9-1/6= ?  $\frac{7}{9} -\frac{1}{6} =\frac{11}{18} =0,61$

e) 3-7/8-1/5= ?  $\frac{3-7}{8} -\frac{1}{5} =\frac{-4}{8} -\frac{1}{5} =-\frac{7}{10} =-0,7$

f) 1/6+7/10 =? $\frac{1}{6} +\frac{7}{10} =\frac{13}{15} =0,86$
