Question

/- kreska ułamkowa
1i7/8 * (-6)
-1i3/4:8
1i1/3*0,5
-1,5:(-2i1/3)
-1i3/4+7i1/5
-2i3/8-1/12
-0,75-(1i2/3)
proszę o dokładne obliczenia a nie tylko odpowiedzi. Dam najlepszą!

Answer 1

1)=15/8*(-6)=15/8*(-6/1)=-45/4=-11i 1/4

2)=-7/4:8/1=-7/4*1/8=-7/32

3)=4/3*5/10=10/15=2/3

4)=-15/10:(-7/3)=-15/10*(-3/7)=45/70=9/14

5)=-7/4+36/5=-35/20+144/20=109/20=5 i 9/20

6)=-19/8-1/12=-114/48-4/48=-118/48=-2 i 22/48=-2 i 11/24

7)=-75/100-5/3=-225/300-500/300=-725/300=-2 i 125/300=-2 i 25/60=-2 i 5/12

Answer 2

1 i 7/8 * (-6) =
= 15/8 * (-6) =
= 45/4 =
= -11 i 1/4

-1 i 3/4 : 8 =
= -7/4 * 1/8 =
= -7/28 =
= - 0,25

1 i 1/3 * 0,5 =
= 4/3 * 1/2 =
= 2/3

-1,5 : (-2 i 1/3) =
= -15/10 : (-7/3) =
= -15/10 * (-3/7) =
= 45/70 =
= 9/14

-1 i 3/4 + 7 i 1/5 =
= -7/4 + 36/5 =
= -35/20 + 144/20 =
= 109/20 =
= 5 i 9/20

-2 i 3/8 - 1/12 =
= -19/8 - 1/12 =
= -57/24 - 2/24 =
= -59/24 =

= -2 i 11/24

-0,75 - (1 i 2/3) =
= -3/4 - 5/3 =
= - 9/12 - 20/12 =
= -29/12 =
= -2 i 5/12
