Question

oblicz:

(3¼ - 1.5) * (-2⅛ + ¼) : (2.25 - 3½) : ⅔+ ⅛

znak : pomiedzy (-2⅛ + ¼) a (2.25 - 3½) to powinna byc kreska ułamkowa czyli rownanie powinno byc w ułamku

wynik to

Answer 1

(3 1/4-1,5)*(-2 1/8+1/4)     (13/4-3/2)*(-17/8+1/4)     7/4*(-15/8)

----------------------------- =  ---------------------------- = ---------------- =

(2,25-3 1/2):2/3+1/8          (9/4-7/2)*2/3+1/8           -5/4*3/2+1/8

 

  -105/32

=---------- =-105/32*(-8/14)=105/56=1 49/56 =1 7/8

   -14/8

Answer 2

(3¼ - 1.5) * (-2⅛ + ¼) | (2.25 - 3½) : ⅔+ ⅛ =
= (3,25 - 1,5) * (-2,125 + 0,250) | (2,25 - 3,5) : 2/3 + 1/8 =
=  1,75 * (-1,875) | -1,25 : 2/3 + 1/8 =

= -3,28125 | -5/4  : 2/3 + 1/8 =
= - 3,28125 | (-5/4)  * 3/2  + 1/8 =
= -3,28125| -15/8 + 1/8 =
= -3,28125 | -14/8 =
= -3,28125 | -1,75=
= -3,28125 : (-1,75) = 
= 1,875 =
= 1 i 7/8
