Question

(1) 13/2 - 1/4 - 5/6=
(2) -2/11 + 11/2 - 12/11=
(3) -5/3 - 4/3=
(4) -3/10 - 2/10 + 4/10=​

Answer 1

Respuestas:

a $\frac{13}{2}-\frac{1}{2}-\frac{5}{6}=\frac{31}{6}\quad \left(\mathrm{Decimal:\quad }\:5.16666\dots \right)$

b $-\frac{2}{11}+\frac{11}{2}+\frac{12}{11}=\frac{141}{22}\quad \left(\mathrm{Decimal:\quad }\:6.40909\dots \right)$

c $-\frac{5}{3}-\frac{4}{3}=-3$

d $-\frac{3}{10}-\frac{2}{10}+\frac{4}{10}=-\frac{1}{10}\quad \left(\mathrm{Decimal:\quad }\:-0.1\right)$
