Question

Oblicz ułamki:
7 i 1/8 -5 i 3/4=...
15*4 i 2/3=...
1 i 1/3* 3 i 3/4=...
3i 3/4: 12=...
7 i 1/4: 1 i 4/7=...
(2 i1/2+ 4 i1/6):1 i 1/3- 1/8=...

Answer 1

7 i 1/8 - 5 i 3/4 = 7 i 1/8 - 5 i 6/8 = 6 i 9/8 - 5 i 6/8 = 1 i 3/8
15 * 4 i 2/3 = 15 * 14/3 = 210/3 = 70
1 i 1/3 * 3 i 3/4 = 4/3 * 15/4 = 5
3 i 3/4 : 12 = 15/4 * 1/12 = 5/16
7 i 1/4 : 1 i 4/7 = 29/4 * 7/11 = 203/44 = 4 i 27/44
(2 i 1/2 + 4 i 1/6) : 1 i 1/3 - 1/8 = (2 i 3/6 + 4 i 1/6 ) : 1 i  8/24 - 3/24 = 6 i 4/6 : 1 i 5/24 = 40/6 * 24/29 = 160/29 = 5 i 15/29
