3/8 + 1/2 = 3/8 + 4/8 = 7/8

Привет! Давай решим эти примеры на сложение дробей. В каждом столбце нужно прибавлять указанное сверху число к каждой дроби в списке. ### Столбец Г (прибавляем $3/8$) 1. $3/8 + 1/2 = 3/8 + 4/8 = 7/8$ 2. $3/8 + 1/6 = 9/24 + 4/24 = 13/24$ 3. $3/8 + 3/7 = 21/56 + 24/56 = 45/56$ 4. $3/8 + 3/16 = 6/16 + 3/16 = 9/16$ 5. $3/8 + 1/4 = 3/8 + 2/8 = 5/8$ 6. $3/8 + 2/8 = 5/8$ 7. $3/8 + 7/12 = 9/24 + 14/24 = 23/24$ 8. $3/8 + 3/4 = 3/8 + 6/8 = 9/8 = 1 1/8$ 9. $3/8 + 5/24 = 9/24 + 5/24 = 14/24 = 7/12$ 10. $3/8 + 5/6 = 9/24 + 20/24 = 29/24 = 1 5/24$ 11. $3/8 + 7/8 = 10/8 = 5/4 = 1 1/4$ 12. $3/8 + 1/4 = 3/8 + 2/8 = 5/8$ 13. $3/8 + 13/32 = 12/32 + 13/32 = 25/32$ 14. $3/8 + 1 7/16 = 6/16 + 1 7/16 = 1 13/16$ 15. $3/8 + 11/72 = 27/72 + 11/72 = 38/72 = 19/36$ ### Столбец Д (прибавляем $1 1/9$) 1. $1 1/9 + 5/6 = 1 2/18 + 15/18 = 1 17/18$ 2. $1 1/9 + 7/12 = 1 4/36 + 21/36 = 1 25/36$ 3. $1 1/9 + 1 1/4 = 1 4/36 + 1 9/36 = 2 13/36$ 4. $1 1/9 + 5/7 = 1 7/63 + 45/63 = 1 52/63$ 5. $1 1/9 + 19/36 = 1 4/36 + 19/36 = 1 23/36$ 6. $1 1/9 + 1/10 = 1 10/90 + 9/90 = 1 19/90$ 7. $1 1/9 + 2 1/6 = 1 2/18 + 2 3/18 = 3 5/18$ 8. $1 1/9 + 3/8 = 1 8/72 + 27/72 = 1 35/72$ 9. $1 1/9 + 11/27 = 1 3/27 + 11/27 = 1 14/27$ 10. $1 1/9 + 4 5/12 = 1 4/36 + 4 15/36 = 5 19/36$ 11. $1 1/9 + 1/3 = 1 1/9 + 3/9 = 1 4/9$ 12. $1 1/9 + 2 8/9 = 3 9/9 = 4$ 13. $1 1/9 + 1/8 = 1 8/72 + 9/72 = 1 17/72$ 14. $1 1/9 + 5/18 = 1 2/18 + 5/18 = 1 7/18$ 15. $1 1/9 + 1/2 = 1 2/18 + 9/18 = 1 11/18$ ### Столбец Е (прибавляем $2 1/4$) 1. $2 1/4 + 1/14 = 2 7/28 + 2/28 = 2 9/28$ 2. $2 1/4 + 3/8 = 2 2/8 + 3/8 = 2 5/8$ 3. $2 1/4 + 1 1/6 = 2 3/12 + 1 2/12 = 3 5/12$ 4. $2 1/4 + 2/5 = 2 5/20 + 8/20 = 2 13/20$ 5. $2 1/4 + 1/10 = 2 5/20 + 2/20 = 2 7/20$ 6. $2 1/4 + 1 1/2 = 2 1/4 + 1 2/4 = 3 3/4$ 7. $2 1/4 + 5/8 = 2 2/8 + 5/8 = 2 7/8$ 8. $2 1/4 + 3/7 = 2 7/28 + 12/28 = 2 19/28$ 9. $2 1/4 + 4 1/3 = 2 3/12 + 4 4/12 = 6 7/12$ 10. $2 1/4 + 7/25 = 2 25/100 + 28/100 = 2 53/100$ 11. $2 1/4 + 4/5 = 2 5/20 + 16/20 = 2 21/20 = 3 1/20$ 12. $2 1/4 + 1 1/20 = 2 5/20 + 1 1/20 = 3 6/20 = 3 3/10$ 13. $2 1/4 + 2/9 = 2 9/36 + 8/36 = 2 17/36$ 14. $2 1/4 + 1/12 = 2 3/12 + 1/12 = 2 4/12 = 2 1/3$ 15. $2 1/4 + 1/4 = 2 2/4 = 2 1/2$
