Вычисли 23/45-12/45+21/45 109/250-(16/250+63/250) 57/190-(32/190-12/190) 35/67+(15/67-9/67) (42/56+8/56)-29/56 203/300+(190/300-150/300)

Answer 1

Ответ:

23/45 - 12/45 + 21/45 = 32/45

109/250 - (16/250 + 63/250) = 30/250

57/190 - ( 32/190 - 12/190) = 37/190

35/67+(15/67-9/67)= 29/67

(42/56+8/56)-29/56= 21/56

203/300+(190/300-150/300)=163/300

Answer 2

Давайте выполним данные математические операции:

1. 23/45 - 12/45 + 21/45 = (23 - 12 + 21) / 45 = 32/45.

2. 109/250 - (16/250 + 63/250) = 109/250 - (79/250) = (109 - 79) / 250 = 30/250 = 3/25.

3. 57/190 - (32/190 - 12/190) = 57/190 - 20/190 = (57 - 20) / 190 = 37/190.

4. 35/67 + (15/67 - 9/67) = 35/67 + 6/67 = (35 + 6) / 67 = 41/67.

5. (42/56 + 8/56) - 29/56 = (42 + 8 - 29) / 56 = 21/56 = 3/8.

6. 203/300 + (190/300 - 150/300) = 203/300 + 40/300 = (203 + 40) / 300 = 243/300 = 27/33 = 9/11.

Итак, результаты вычислений:

1. 32/45
2. 3/25
3. 37/190
4. 41/67
5. 3/8
6. 9/11
