4 1/2 : 2 1/4 = ​



Odpowiedź :

3 9/11 + 2 1/4 = 3 36/44 + 2 11/44 = 6 3/44

5 1/4 - 1 1/6 = 5 3/12 - 1 2/12 = 4 1/12

4 1/2 ÷ 2 1/4 = 4 2/4 ÷ 2 1/4 = 2

Odpowiedź:

3 9/11 + 2 1/4 = 3 36/44 + 2 11/44 = 5 47/44 = 6 3/44

5 1/4 - 1 1/6= 5 3/12- 1 2/12= 4 1/12

4 1/2 : 2 1/4= 9/2 : 9/4= 9/2× 4/9 = 2/1= 2
