Answer:

-29/70

Step-by-step explanation:

-13/20+11/14+(-5/4)+7/10

-13/20+11/14+(-5/4)+7/10= (-13/20+7/10)+(11/14+(-5/4))

-13/20+11/14+(-5/4)+7/10= (-13/20+7/10)+(11/14+(-5/4)) = (-13+14/20)+(22+(-35)/28)

-13/20+11/14+(-5/4)+7/10= (-13/20+7/10)+(11/14+(-5/4)) = (-13+14/20)+(22+(-35)/28)= 1/20+(-13/28)

-13/20+11/14+(-5/4)+7/10= (-13/20+7/10)+(11/14+(-5/4)) = (-13+14/20)+(22+(-35)/28)= 1/20+(-13/28)= 7+(-65)/140

-13/20+11/14+(-5/4)+7/10= (-13/20+7/10)+(11/14+(-5/4)) = (-13+14/20)+(22+(-35)/28)= 1/20+(-13/28)= 7+(-65)/140= 7-65/140

-13/20+11/14+(-5/4)+7/10= (-13/20+7/10)+(11/14+(-5/4)) = (-13+14/20)+(22+(-35)/28)= 1/20+(-13/28)= 7+(-65)/140= 7-65/140= -58/140

-13/20+11/14+(-5/4)+7/10= (-13/20+7/10)+(11/14+(-5/4)) = (-13+14/20)+(22+(-35)/28)= 1/20+(-13/28)= 7+(-65)/140= 7-65/140= -58/140= (-58/140)÷2

-13/20+11/14+(-5/4)+7/10= (-13/20+7/10)+(11/14+(-5/4)) = (-13+14/20)+(22+(-35)/28)= 1/20+(-13/28)= 7+(-65)/140= 7-65/140= -58/140= (-58/140)÷2= -29/70
