Answer 1

Răspuns:

a) 4/10+35/12-7/12:25/10 = 4/10 +35/12-7/12*10/25 = 4/10+35/12-7/30 = 24+175-14/60 = 185/60 = 37/12

b) 6/9 +2/3*3/4 +2/9 = 6/9+1/2+2/9 = 8/9+1/2 = 16+9/18 = 25/18

c) 3/4*8/9 - 3/4:6 = 2/3-3/4*1/6 = 2/3-1/8 = 16-3/24 = 13/24

d)23/10*10/23*10 + 1/3 = 1+1/3 = 4/3

e)7/9:1/49+21/9+1= 7/9*49+21/9+1 = 273+21+9/9 = 303/9=101/3 (desi eu cred ca la primul termen ar fi trebuit sa fie inmultire..:)

f)0.25*8+1/10000*100000 = 2+10 = 12
