Oblicz: a.18/7 x (-6/25) x 35/36 = b. - 6/7 : (- 2 i 2/3) x 1 i 5/9 = c. 8/15 x (-20/9) x (-81/64) =
Tylko proszę też o obliczenia, a nie same wyniki :)
Zgłoś nadużycie!
A.18/7 x (-6/25) x 35/36 = = 18/7* (-7/30)= = -18/30= = -6/10= =-3/5 b. - 6/7 : (- 2 i 2/3) x 1 i 5/9 = = -6/7:(8/3)*14/9= = -6/7*(-7/12)= = 1/2 c. 8/15 x (-20/9) x (-81/64) = = -32/3*(- 9/4)= = 3/2 = 1 i 1/2

A.18/7x(-6/25)x35/36 = 0,6168*0,97=ok.-0,63 b. - 6/7 : (- 2 i 2/3) x 1 i 5/9 =-0,86:2,67*1,55=ok.-0,50 c. 8/15 x (-20/9) x (-81/64) =0,53*-2,22*(-1,26)=ok.1,48
= 18/7* (-7/30)=
= -18/30=
= -6/10=
=-3/5
b. - 6/7 : (- 2 i 2/3) x 1 i 5/9 =
= -6/7:(8/3)*14/9=
= -6/7*(-7/12)=
= 1/2
c. 8/15 x (-20/9) x (-81/64) =
= -32/3*(- 9/4)=
= 3/2
= 1 i 1/2
b. - 6/7 : (- 2 i 2/3) x 1 i 5/9 =-0,86:2,67*1,55=ok.-0,50
c. 8/15 x (-20/9) x (-81/64) =0,53*-2,22*(-1,26)=ok.1,48
Jeżeli x znaczy razy*
