b)0,6 +4/6 -2: 1/5


c)7/2 : 3/5 -9/4 x 2/3 + 1/6 x 3/2



d)(3/9) + 5/3 :) -2/9)





por favor responder todas em forma de fraçao

Answer 1

b)0,6 +4/6 -2: 1/5

0,6=6/10

então: 6/10+4/6-2/1/5

6/10+4/6-10=-524/60 simplifica por 2 duas vezes

=-262/30 = -131/15
-----------------------------------------------

c)7/2 : 3/5 -9/4 x 2/3 + 1/6 x 3/2

(7/2)/3/5-18/12+3/12

(7/2)/3/5-15/12

7/2/39/60

420/78 = 210/39 = 70/13

--------------------------------------

(3/9) + 5/3 :(-2/9)

3/9 -45/6

-129/18
