3/5 - 1/5 =

Привет! Давай решим примеры на вычитание дробей. Напоминаю, чтобы вычесть дроби с разными знаменателями, нужно привести их к общему знаменателю. **Левый столбик:** 1) 3/5 - 1/5 = 2/5 2) 7/20 - 3/20 = 4/20 = 1/5 3) 12/16 - 3/16 = 9/16 4) 16/27 - 8/27 = 8/27 5) 10/9 - 8/9 = 2/9 6) 9/10 - 2/10 = 7/10 7) 5/13 - 1/13 = 4/13 8) 1/2 - 1/4 = 2/4 - 1/4 = 1/4 9) 5/9 - 1/3 = 5/9 - 3/9 = 2/9 10) 7/10 - 3/5 = 7/10 - 6/10 = 1/10 11) 16/27 - 1/9 = 16/27 - 3/27 = 13/27 12) 3/5 - 13/45 = 27/45 - 13/45 = 14/45 13) 1/3 - 8/27 = 9/27 - 8/27 = 1/27 14) 1/2 - 1/3 = 3/6 - 2/6 = 1/6 15) 3/5 - 1/3 = 9/15 - 5/15 = 4/15 **Правый столбик:** 1) 7/8 - 2/3 = 21/24 - 16/24 = 5/24 2) 3/4 - 4/7 = 21/28 - 16/28 = 5/28 3) 9/16 - 11/24 = 27/48 - 22/48 = 5/48 4) 11/12 - 11/18 = 33/36 - 22/36 = 11/36 5) 5/12 - 1/3 = 5/12 - 4/12 = 1/12 6) 1/5 - 3/20 = 4/20 - 3/20 = 1/20 7) 7/8 - 5/12 = 21/24 - 10/24 = 11/24 8) 9/10 - 1/6 = 27/30 - 5/30 = 22/30 = 11/15 9) 8/18 - 8/27 = 4/9 - 8/27 = 12/27 - 8/27 = 4/27 10) 12/13 - 15/26 = 24/26 - 15/26 = 9/26 11) 7/16 - 5/24 = 21/48 - 10/48 = 11/48 12) 9/12 - 1/3 = 3/4 - 1/3 = 9/12 - 4/12 = 5/12 13) 9/50 - 3/40 = 36/200 - 15/200 = 21/200 14) 1 - 1/2 = 2/2 - 1/2 = 1/2 15) 1 - 11/25 = 25/25 - 11/25 = 14/25
