a = ( 200 - 125 + 1 / 4 ) × 4
a = ( 75 + 1 / 4) × 4
a = ( 300 / 4 + 1 / 4) × 4
a = 301 / 4 × 4
a = 301
3 intregi si 1 / 8 = ( 3 × 8 + 1) / 8 = 25 / 8
1 intreg si 1 / 10 = ( 1 × 10 + 1) / 10 = 11 / 10
8 = 2³
10 = 2 × 5
_________
c m m m c ( 8 si 10 ) = 2³ × 5 = 40
b= 25 / 8 - 11 / 10
b = 125 / 40 - 44 / 40
b = 81 / 40 = 2 intregi si 1 / 40 = 2,025
a > b , 301 > 2, 025
Daca dupa paranteza rotunda este : 4 , atunci valoarea lui a este:
a = 301 / 4 : 4 = 301 / 4 × 1 / 4 = 301 / 8 = 37 intregi si 5 / 8 = 37,625
a > b; 37,625 > 2,025
