Question

Jaki będzie wynik ułamków 1/2+3/4 1/3+7/9 5/6+1 1/4 1 3/5+ 2 4/15 2 1/4+1 2/3 1 5/6+7/9

Answer 1

1/2 + 3/4 = 2/4 + 3/4 = 5/4 = 1 i 1/4

1/3 + 7/9 = 3/9 + 7/9 = 10/9 = 1 i 1/9

5/6 + 1 i 1/4 = 10/12 + 15/12 = 25/12 = 2 i 1/12

1 i 3/5 + 2 i 4/15 = 8/5 + 34/15 = 24/15 + 34/15 = 58/15 = 3 i 13/15

2 i 1/4 + 1 i 2/3 = 9/4 + 5/3 = 27/12 + 20/12 = 47/12 = 3 i 11/12

1 i 5/6 + 7/9 = 11/6 + 7/9 = 33/18 + 14/18 = 47/18 = 2 i 11/18

Answer 2

1/2+3/4 =5/4=1,251/3+7/9 =10/9=1 1/9
5/6+1 1/4 =10/12+15/12=25/12= 2 1/12
1 3/5+ 2 4/15 =24/15+34/15=58/15=3 13/15
2 1/4+1 2/3=27/12+20/12=47/12=3 11/12
1 5/6+7/9=33/18+14/18=47/18=2 11/18
