Odpowiedź:
1/2 + 3/14 = 7/14 + 3/14 = 10/14 = 5/7
3/5 + 7/2 = 6/10 + 35/10 = 41/10 = 4 i 1/10
33/100 + 1/20 = 33/100 + 5/100 = 38/100 = 19/50
42/3 + 1 i 1/2 = 84/6 + 1 i 3/6 = 1 i 87/6 = 15 i 3/6 = 15 i 1/2
2/3 + 3/4 = 8/12 + 9/12 = 17/12 = 1 i 5/12
Odpowiedź:
1/2 + 3/14 = 7+3/14 = 10/4 = 5/7
3/5 + 7/2 = 6 + 35/10 = 41/10
33/100 + 1/20 = 33+5/100 = 38/100= 19/50
42/3 + 1 i 1/2 = 14 + 1 i 1/2 = 15 i 1/2 =
2/3 + 3/4 = 8 + 9/12 = 17/12
Szczegółowe wyjaśnienie:
10/4 skracam przez 2
38/100 skracamy przez 2
