Question

Сравните дроби:3/5 и 2/5. б)5/6 и 4/5. в)23/24 и 22/23.
Вычислите:2/13 + 5/13 б)4/5-3/4 в)2/15+1/3 г)5/16 -1/24.

Answer 1

3/5 > 2/5
5/6 > 4/5 // 25/30 > 24/30
23/24 > 22/23 // 529/552 > 528/552 

2/13+5/13 = 7/13
4/5 - 3/4 = 16/20 - 15/20 = 1/20
2/15+1/3 = 2/15 + 5/15 = 7/15
5/16 - 1/24 = 120/384 - 16/384 = 104/384
