Question

valendo 30 pontossssssssssss

Determine a soma algébrica sob a forma de fração irredutível. 20 pontos

4/5+ 2-1/4=

1/3 - 1/2 + 5/6 - 8/3=

7-(1-4/3)=

- 7/12 + (-4/14+/6-3/4)=

|-1/2+1/3|=

2,5 - (-3/2 - 2) =

-0,01+(-1/100) + 1,03=

|-5+7/20-32/10|=

Answer 1

4/5+ 2-1/4= 16/20 + 40/20 -5/20 = 51/20.

1/3 - 1/2 + 5/6 - 8/3=  2/6-3/6+5/6-8/3= -2

7-(1-4/3)= 21/3+1/3=22/3.

- 7/12 + (-4/14+/6-3/4)= 69/60-25/60= 44/60.

( me perdoa anjo, foram as únicas que consegui kk
