Kesmalarning o‘lchami sifatida qaralgan sonlar ustida arifmetik amallar ta’rifi va amallar bajarish xossalari

Kesmalarning o‘lchami sifatida qaralgan sonlar ustida arifmetik amallar ta’rifi va amallar bajarish xossalari.

1. 3/4 + 1/2 = (3*2 + 4*1) / (4*2) = 11/8

2. 5/6 - 1/3 = (5*1 - 6*2) / (6*3) = -1/6
3. 2/3 * 3/5 = (2*3) / (3*5) = 6/15 = 2/5
4. 7/8 / 1/4 = (7/8) * (4/1) = 28/8 = 7/2
5. 2 + 3/4 = (2*4 + 3*1) / 4 = 11/4
6. 6 - 2/3 = (6*3 - 2*1) / 3 = 16/3
7. 1/2 + 1/3 - 1/4 = (1*6 + 1*4 - 1*3) / (2*3*4) = 7/24
8. 5/6 * 2 = (5*2) / 6 = 5/3
9 . 4/5 / 2/3 = (4/5) * (3/2) = 12/10 = 6/5
10. 3/4 - 2/3 = (3*3 - 4*2) / (4*3) = -5/12
