Question

Resolver los siguientes ejercicios
1=. (2+1/2-23/4-11/5) (-10/3-2)
2=. (1/3+2/5-1/2).|.(1 1/2-1/3)
Son fracciones

Answer 1

1)1(2/5)+(9/(21))-(1/(10))
Los convertimos a fracciones impropias
(((5×1)+2)/5)+(9/(21))-(1/(10))
(7/5)+(3/7)-(1/(10))
las convertimos en fracciones homogeneas
mcm(5,7,10)= 70
((7×14)/(5×14))+((3×10)/(7×10))-((1×7)/(...
((98)/(70))+((30)/(70))-(7/(70))
= ((98+30-7)/(70))= ((121)/(70))
Rta. 1(2/5)+(9/(21))-(1/(10))= 121/70
