2 całe i 3/4 - 1 cała i 1/6 =
3 całe i 8/9 + 2 całe i 5/6 =
3 całe i 2/3 - 1 cała i 1/5 =
1 cała i 1/8 + 2 całe i 10/11 =
3 całe i 1/4 - 2 całe i 5/8 =
1 cała i 5/8 + 2 całe i 11/14 =
4 całe i 1/6 - 2 całe i 3/8 =
1,5 + 5/8 =
2,25 - 3/16 =
3/5 + 1,7 =
5 całych i 3/8 - 4,7 =
19/20 + 0,19 =

Bardzo bardzo proszę o poprawne rozwiązanie :) .
Daję naj .

Answer 1

2 3/4-1 1/6 = 11/4-7/6 = 33/12-14/12 = 19/12 = 1 7/12

3 8/9+2 5/6 = 35/9+17/6 = 70/18+51/18 = 121/18 = 6 13/18

3 2/3-1 1/5 = 11/3-6/5 = 55/15-18/15 = 37/15 = 2 7/15

1 1/8+2 10/11 = 9/8+32/11 = 99/88+256/88 = 4 3/88

3 1/4-2 5/8 = 13/4-21/8 = 26/8-21/8 = 5/8

1 5/8+2 11/14 = 13/8+39/14 = 91/56+156/56 = 247/56 = 4 23/56

4 1/6-2 3/8 = 25/6-19/8 = 100/24-57/24 = 43/24 = 1 19/24

1,5+5/8 = 1 5/10+5/8 = 1 1/2+5/8 = 5/2+5/8 = 20/8+5/8 = 25/8 = 3 1/8

2,25-3/16 = 2 25/100-3/16 = 2 1/4-3/16 = 9/4-3/16 = 36/16-3/16 = 33/16 = 2 1/16

3/5+1,7 = 3/5+1 7/10 = 3/5+17/10 = 6/10+17/10 = 23/10 = 2 3/10

5 3/8-4,7 = 43/8-4 7/10 = 43/8-47/10 = 215/40-188/40 = 27/40

19/20+0,19 = 19/20+19/100 = 95/100+19/100 = 114/100 = 1 14/100 = 1 7/50
