Szczegółowe wyjaśnienie:
a) 4 3/7 - ( - 1 4/7) = 31/7 - (- 11/7) = 31/7 + 11/7 = 42/7 = 6
b) - 5 3/5 - 2 1/5 = - 18/5 - 11/5 = - 29/5 = - 5 4/5
c) 6,37 - (- 4,15) = 637/100 - (- 415/100) = 637/100 + 415/100 = 1052/100 =
= 10,52
d) - 8,1 - 2,45 = - 81/10 - 245/100 = - 810/100 - 245/100 = - 1055/100 = - 10,55
