Mnożenie:

4* (-2.5)=

-4 1/5 * 15 =

24*( -3 1/3) =

-18*1 5/6 =

(-1 1/3 ) do potęgi 3 =

(-1/2) do potęgi 2 =

0,2 * ( -2.4 ) =

-2.5 * 10 =

Dzielenie : ( UKOŚNIK ROBI ZA KRESKĘ UŁAMKOWĄ !!! )

3/4 : ( - 5/8 ) =

-7/15 : (-7/10) =

Answer 1

1. 4 * (-2,5) = (-10)

2. (-4 1/5) * 15 = (-63)

3. 24 * (-3 1/3) = (-80)

4. (-18) * 1 5/6 = (-33)

5. (-1 1/3)szescian = 1 1/9

6. (-1/2)kwadrat = 1/4

 

7. 3/4 : (-5/8) = 3/4 * (-8/5) = (-24/20) = (-6/5) = (-1 1/5)

8. (-7/15) : (-7/10) = (-7/15) * (-10/7) = 1/2

tak mi sie wydaje *.*

Answer 2

a)4*(-2,5)=-10

b)-4 1/5 * 15= -21/5 * 15 = -315/5 = -63

c)24 * (-3 1/3)= 24 * (-10/3)= -240/3 = -80

d)-18 * 1 5/6 = -18 * 11/6 = -198/6 = -33

e)(-1/2)^2= -0,5^2 =0,25

f)0,2 * (-2,4)= -0,48

g)(-2,5) * 10 = 25

 

h)3/4 : (-5/8) = 3/4 * (-8/5) = -24/20 = - 6/5

i)(-7/15) : (-7/10)= (-15/7) * (-10/7) = 150/49
