10. 3,75 ; 3/4 ; 5 2/7 ; 8/6 ; 72%
= 375/100 ; 3/4 ; 37/7 ; 8/6 ; 72/100
= 7875/2100 ; 1575/2100 ; 11.100/2100 ; 2800/2100 ; 1512/2100
= 1512/2100 ; 1575/2100 ; 2800/2100 ; 7875/2100 ; 11.100/2100
= B.

11. 6 × 7/18 : 0,875 = 6 × 7/18 : 875/1000
= 6 × 7/18 × 1000/875 = 42.000/15.750 : 10/10
= 4200/1575 : 25/25 = 168/63 : 3/3 = 56/21
= C.

12. 23 1/2 - 3 2/5 = 47/2 - 17/5 = 235/10 - 34/10
= 201/10 : 0,3 = 201/10 : 3/10 = 201/10 × 10/3
= 2010/30 : 10/10 = 201/3 = D.

13. 2,16 = 216/100 = C.
