Pomoże ktoś? W tym przykładzie a. jest kreska ułamkowa.
a. 6i3/4 * (2i1/3 - 1i5/6) - 5/8
3i3/4 *11/15 - 1/2
c. 2,8 + 2,8 * 3 i5/7 + 2,8 * 3i5/7 *35/52 + 2,8 3i5/7 * 35/52 * 0,55

a. 6i3/4 * (2i1/3 - 1i5/6) - 5/8=
=6i(3/4)·(1i8/6 - 1i5/6) - 5/8 =
=6i3/4 ·(3/6) -5/8=
=27/4 · 1/2 - 5/8 =
=27/8 - 5/8 = 22/8 = 2 i (6/8) = 2 i (3/4) wartość licznika
3i3/4 *11/15 - 1/2 =
=15/4·11/15 - 1/2 =
= 165/60 - 30/60 =
= 135/60 = 2 i (15/60) = 2 i (1/4) wartość mianownika
co daje:
2i(3/4) / 2i(1/4) = (15/4) / (9/4) = (15/4) x (4/9) = 60/36 = 10/6 =
= 5/3 = 1 i (2/3)
c. 2,8 + 2,8 * 3 i5/7 + 2,8 * 3i5/7 *35/52 + 2,8 3i5/7 * 35/52 * 0,55=
= 2,8(1+3i5/7 + 3i5/7 * 35/52 + 2,8 3i5/7 * 35/52 * 0,55)=
= 2,8(1+3i5/7(1+35/52 + 35/52 * 0,55))=
= 2,8(1+3i5/7(1+35/52(1 + 0,55)))=
= 2,8(1+3i5/7(1+7/13*55/4))=
= 2,8(1+3i5/7(1+385/52))=
= 2,8(1+3i5/7*437/52)=
= 2,8(1+26/7*437/52) = 2,8(1+1/7*437/2) = 2,8(1+437/14) = 2,8(451/14) =
= 14/5 * 451/14 = 451/5 = 90 i 1/5 UFFFFF
