Proszę niech ktoś obliczy:
4 1/4 - (1 1/2 + 2/3 + 1 5/6)
2 1/3 * 3/4 + 5 3/8 : 5 1/2
4 1/4-(1 1/2+2/3+1 5/6)=4 1/4-(1 3/6+4/6+1 5/6)=4 1/4-2 12/6=4 1/4-4=1/4
2 1/3*3/4+5 3/8:5 1/2=2 1/4+5 3/8:5 3/4=2 1/4+1 1/2=2 1/4+1 2/4=3 3/4
4 1/4 - (1 1/2 + 2/3 + 1 5/6) = 17/4 - (3/2 + 2/3 + 11/6) = 17/4 - (9/6 + 4/6 + 11/6) = 17/4 - 24/6 = 51/12 - 48/12 = 3/12 = 1/4
2 1/3 * 3/4 + 5 3/8 : 5 1/2 = 7/3 * 3/4 + 43/8 : 11/2 = 7/4 + 43/8 * 2/11 = 7/4 + 43/44 = 77/44 + 43/44 = 120/44 = 30/11 = 2 8/11
