3 19/25 - ( 2/5 ) do potęgi 2 =
2 5/6 * 3/17 + 3 =
5 4/15 - 1 2/3 =
1 5/6 : 1/3 - 1 9/10 =
4 3/2 * 3/4

Tłumaczenie :
Np. 2/3 <---- ułamek ( dwie trzecie )
Np. 5 4/15 ( 5 to całość z ułamkiem )
Np. 3/2 * 3/4 ( * gwiazdka oznacza mnożenie )
Dam naj : ) Z góry dziękuję <3

3 i 19/25 - (2/5)^2 = 3 i 19/25 - 4/25 =3 i 15/25 i to skaracamy i jest 3 i 3/5
2 i 5/6 * 3/17 + 3 = 17/6 * 3/17 + 3 = 3 i 1/2
5 i 4/15 - 1 i 2/3 = 79/15 - 5/3 = 79/15 - 25/15 = 54/15 = 3 i 9/15 = 3 i 3/5
1 i 5/6 : 1/3 - 1 i 9/10 = (11/6 * 3/1) - 1 i 9/10 = 11/2 - 19/10 = 55/10 - 19/10 = 36/10 = 3 i 6/10 a to skaracamy i jest 3 i 3/5
4 i 3/2 * 3/4 = 11/2 * 3/4 = 33/8 = 4 i 1/8
2 i 1/10 + 1 i 1/2 = 21/10 + 3/2 = 21/10 + 15/10 = 36/10 = 3 i 6/10 a to jest 3 i 3/5
(1/2)^2 + 3 i 1/4 = 1/4 + 3 i 1/4 = 1/4 + 13/4 = 14/4 = 7/2 = 3 i 1/2
9 i 1/6 - 5 i 2/3 = 55/6 -17/3 = 55/6 - 34/6 = 21/6 = 3 i 3/6 a to jest 3 i 1/2
