1/10 + 1/4 = 2/20 + 5/20 = 7/20 3/10 + 1/15 = 9/30 + 2/30 = 11/30 5/6 + 3/4 = 10/12 + 9/12 = 19/12 = 1 7/12 9/14 + 1/21 = 27/42 + 2/42 = 29/42 7/12 + 4/9 = 21/36 + 16/36 = 37/36 = 1 1/36 5/18 + 17/24 = 20/72 + 51/72 = 71/72 11/12 + 3/8 = 22/24 + 9/24 = 31/24 = 1 7/24 5/6 + 29 = 29 5/6
1/10 + 1/4 = = 2/10 + 5/20= = 7/20 3/10 + 1/15 = = 9/30 + 2/30= = 11/30 5/6 + 3/4 = = 10/12 + 9/12= = 19/12= = 1 i 7/12 9/14 + 1/21 = = 27/42 + 2/42= = 29/42 7/12 + 4/9 = = 21/36 + 16/36= = 37/36 = = 1 i 1/36 5/18 + 17/24 = = 20/72 + 51/72= = 71/72 11/12 + 3/8 = = 22/24 + 9/24= = 31/24= = 1 i 7/24 5/6 + 29 = 29 i 5/6 jeśli zamiast 29 miał być ułamek 2/9 , to rozwiązanie jest takie 5/6 + 2/9 = = 15/18 + 4/18 = = 19/18 = = 1 i 1/18
Oblicz. 5/6 - 3/4 = 7/9 - 7/15 = 7/8 - 5/12 = 9/10 - 17/25 = 8/9 - 5/6 = 5/22 - 1/33 = 19/24 - 17/32 = 13/14 - 11/21 = Dam naj za szybką i dobrą odp. !! (: ( Ukośnik to kreska ułamkowa )...
Oblicz. a) 6 85/100- 5 96/100 = b) 6 81/100 - 5 99/100 = c) 6 74/100 - 5 96/100 = ( Ukośnik to kreska ułamkowa ) Dam naj za szybką i dobrą odp....
