Question

OBLICZ 75 % WARTOŚCI WYRAŻENIA :
8½ - (-3½ * ¹/₇ -3) :(-7)

Answer 1

8½ - (-3½ * ¹/₇ -3) :(-7) = 8½ - ( (-½)-3 ):(-7) =
= 8½ - ( -3,5 ) : (-7) = 8½ - 0,5 = 8

75%=0,75=¾

¾ * 8 = 6

Answer 2

OBLICZ 75 % WARTOŚCI WYRAŻENIA :
8½ - (-3½ * ¹/₇ -3) :(-7)=8½ - (-7/2 * ¹/₇ -3) :(-7)=
8½ - (-1/2 -3) :(-7)=8½ - (-3 i 1/2 ) *(-1/7)=8½ - (-7/2 ) *(-1/7)=
8½ -1/2=8

75 % z 8=3/4*8=6

Answer 3

8½ - (-3½ * ¹/₇ -3) :(-7)
8,5-(-3,5*1/7-3)/(-7) = 8,5-(-35/10*1/7-3)/(-7) = 8,5-(-0,5-3)/(-7) = 8,5-(-3,5)/
(-7) = 8,5-(35/10*1/7) = 8,5-0,5 = 8
75%*8 = 0,75*8 = 6
