c) -2 1/2 : (-1 1/4) · ( - 3/7 ) =-5/2 x -4/5 x -3/7=-1 1/7
d) - 4/9 · ( - 4 ½ ) : ( - 1/12 ) =-4/9 x -9/2 x -12=-24
c) -2 1/2 : (-1 1/4) · ( - 3/7 ) = -5/2 ÷ (-5/4) * (-3/7) = -5/2 * (-4/5) * (-3/7) =
-1 * (-2) * (-3/7) = 2 * (-3/7) = -6/7
d) - 4/9 · ( - 4 ½ ) : ( - 1/12 ) = -4/9 * (-9/2) * (-12) = -2 * (-1) * (-12) = 2 * (-12) = -24
Zad 6.
a) 128 : (-16) · (-5) : (-8) = -8 * 5/8 = -5
b) -25 · (-6) : (-30) · 16 : (-8) = -25 * 6/30 * (-16/8) = -25 * 1/5 * (-2) = -5*(-2)=10
c) 3¾ : 1½ · (-4/15) = 15/4 ÷ 3/2 * (-4/15) = 15/4 * 2/3 * (-4/15) = 30/12 * (-4/15) = 2/3 * (-1) = -2/3
d) -1 1/5 : [-1½ : (-2½)] = -6/5 ÷ [-3/2÷(-5/4)] = -6/5 ÷ [-3/2 * (-4/5)] = -6/5÷6/5 = -6/5 * 5/6 = -1
Ułamki w każdym z przykładów się ładnie skracają, ale nie mogłam tego tutaj pokazać, jednak mam nadzieję, że zrozumiesz mój tok myślenia :)
