a. 5 1/2 x 2,25-4 5/7 : 1 1/12=12,375- 33/7x 21/22= 12,375- 4,5= 7,875

b. (15/4 x 4/5-4,5:3,5):24= (60/20 - 45/10 x 10/35):24=(6/2-45/35):24=(21/7-9/7):24=12/7x 1/24= 12/168= 1/14

c. 11 1/4(5/3-4/3)= 11 1/4x1/3=45/12=3 3/4

d.4 1/8+55/100x3/22= 4 1/8+165/2200=4 1/8+33/440=4,125+0,075=4,2

e. (7/3-16/10): 1,1= (70/30-16/10);1,1=2,7;1,1=2 5/11

f. 10/3+125/100  =  1000/300+375/300 =1375/300=  

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

10/30-125/100   =    1000/300-375/300  = 625/300=

1375/300x300/625=66/30=2,2

g. 3,6

-------- = 3,6;0,12=30

0,12

 

h.     4 8/20-2 15/20          33/20

    1+--------------------= 1+-------------= 1+33/20x (-20/30)= 1+(-660/660)=

        2 15/20-4 8/20            (-33/20)          

=1-1=0
