Odpowiedź:
9 i 1/5:(5 i 3/4 : 2 i 1/5)=
= 46/5 : (23/4 : 11/5) =
= 46/5 : ( 23/4 * 5/11) =
= 46/5 : 115/44 =
= 46/5 * 44/115 =
= 2024/575 =
= 3 i 299/575 = (skracam ułamek przez 23)
= 3 i 13/25
9 i 1/5:(14:7/23)=
= 46/5 : (14 * 23/7) =
= 46/5 : (2 * 23/1)=
= 46/5 : 46/1=
= 46/5 * 1/46=
= 1/5 * 1/1=
= 1/5
6:9/10+3/5:4/5=
= 6 * 10/9 + 3/5 * 5/4 =
= 2 * 10/3 + 3/1 * 1/4=
= 20/3 + 3/4 =
= 6 i 2/3 + 3/4=
= 6 i 8/12 + 9/12=
= 6 i 17/12=
= 7 i 5/12
