Explicație pas cu pas:

a)

1⁷/₈=(1x8+7)/8= 15/8

4³/₄=(4x4+3)/4=19/4

15/8*19/4=185/32

185:32= 5,80

5,80 < 10

-

b)

6³/₅=(6x5+3)/5= 33/5

3¹/₄=( 3x4+1)/4= 13/4

33/5*13/4=429/20

429:20= 21,45

21,45> 10

-

c)

2²/₈=(2x8+2)/8=18/8

5¹/₄=( 5x4+1)/4=21/4

18/8*21/4=189/16

189:16= 11, 80

11,80 >10
