Explicație pas cu pas:
a) a = 2, b= 18
mₐ (a,b) = (2+18)/2 = 20/2 = 10
b) a = 7,25, b = 22,75
mₐ (a,b) = (7,25+22,75)/2 = 30/2 = 15
c) a = 5,5 = 55/10 = 11/2 ;
b = 1,8(3) = (183-18)/90 =165/90 = 11/6
mₐ (a,b) = (³⁾11/2 + 11/6)/2 = (44/6) : 2 = 22/6 = 3,(6)
e) a= 2/6, b=8/6
mₐ (a,b) = (2/6 + 8/6)/2 = (10/6):2 = 5/6 = 0,8(3)
f) a=315, b=1715
mₐ (a,b) = (315 + 1715)/2 = 2030/2 = 1015
d) a = 1-0,8 ; b = 1+0,8
mₐ (a,b) = (1-0,8+1+0,8)/2 = 2/2 = 1
d') a = 1 ; b = 1+0,8
mₐ (a,b) = (1+1+0,8)/2 = 2,8/2 = 1,4
