8/5- (5/8*8/10) + 8/5 podzielić na 2= 8/5 - 40/80 + 8/5 podzielić na dwa = 384/240 - 120/240 + 384/240 podzielić na dwa. = 264/240 + 384/240 podzielić na dwa. = 648/240 podzielić na dwa = 324/120 = 2,7
1 3/5-(5/8*8/10+1 3/5):2= 1 3/5-(1/2+1 3/5):2= 1 3/5- (5/10+16/10):2=1 3/5-21/10:2=1 3/5-21/10 * 1/2= 1 3/5-21/20=8/5-21/20= 32/20-21/20=11/20
