c)[0,16+0,(16)]:0,28:0,(02)-6/7=

(16/100+16/99):28/100:2/99-6/7=

(16/100×100/28+16/99×100/28):2/99-6/7=

[4/7+4/(7×99)]×99/2-6/7=

4/7×99/2+[4/(7×99)]×99/2-6/7=

2×99/7+2/7-6/7=198/7+2/7-6/7=

(200-6)/7=194/7=27 și 5/7

d)(375/999-375/1000):5/37:7/360=

(375/999×37/5-375/1000×37/5):7/360=

(75/27-75×37/1000):7/360=

(25/9-3×37/40):7/360=

(25/9-111/40)×360/7=

1999/360×360/7=1999/7=285 și 5/7
