Question

3 3/4 - 4 1/2 =

2 2/3- 4 3/5 =

6 3/5 * (-2 6/7) =

(-2 2/3) * (-3 1/2) =

(- 3/4) : (-2 1/5) =

(-2 1/5) : 2/3 =

1 3/7 * (2 1/10 - 4 1/2) =

(-4 2/5 + 3 4/10) : 2/15 =

[2 1/2 + (1/2-1 3/4) * 2] : 1/2 =

proszę o to zadanie! ;p

Answer 1

15/4-5/2=15/4-10/4=5/4= 1 1/4

8/3-23/5=40/15-69/15=-29/15=-1 14/15

33/5*(-20/7)=-660/35=-18 6/7

-8/3*(-7/2)=56/6=9 1/3

-3/4:(-11/5)=3/4*5/11=15/44

-11/5*3/2=-33/10=-3,3

10/7*(21/10-9/2)=10/7*(21/10-45/10)=10/7*(-24/10)=-240/70=-24/7=-3 3/7

(-22/5+34/10)*15/2=(-44/10+34/10)15/2=-15/2=-7 1/2

[3/2+(2/4-7/4)*2]*2=[3/2+(-5/4)]*2=[6/4-5/4]*2=1/2
