Prosze o rozwiązanie jak najszybciej. :D

Answer 1

a) 0,5* 1/3= 5/10 * 1/3 = 1/2 * 1/3 =  1/6

b) 0,75* 1/5= 75/100 * 1/5 = 3/4 *1/5 = 3/20

c) 1 1/4 : 1,25= 5/4 : 125/100 = 5/4 * 5/4 = 25/16

d) 0,25 : 1/2= 25/100 : 1/2 = 1/4 * 2 = 2/4 = 1/2

e)0,25* 1/2= 25/100 * 1/2 = 1/4 * 1/2 = 1/8

f) 1,5 : 1/2= 15/10 : 1/2 = 3/2 * 2 = 3

g) 2,125 : 1/8= 2,125 * 8 = 17

h) 0,5 : 1/4= 5/10 : 1/4 = 1/2 * 4 = 2

 

a) 0,2* 1/8= 2/10 * 1/8 = 1/5 * 1/8 = 1/40

b) 1 1/3 * 2,7 = 4/3 * 27/10 = 18/5

c) 1 1/3 * 3 3/4 * 0,2= 4/3 * 15/4 * 2/10 = 5 * 1/5 = 1

d) 3/4 :0,0375= 0,75 : 0,0375 = 20

e) 0,48 : 1 1/7=0,48 : 8/7 = 48/100 * 7/8 = 42/100 = 0,42

f) (2 2/11 : 8/3) * 0,11= (24/11 : 8/3) * 0,11 = (24/11 * 3/8) * 0,11 = 9/11 * 11/100 = 9/100 = 0,09

h) 1,8 : (1 1/3* 6 3/4= 1,8 : (4/3 * 27/4) = 1,8 : 9 = 0,2

Answer 2

a)0,5*1/3=1/2*1/3=1/6

b)0,75*1/5=3/4*1/5=3/20

c)1 1/4:1,25=5/4*100/125=25/25=1

d)0,25:1/2=1/4:1/2=1/4*2/1=1/2

e)0.25*1/2=1/4*1/2=1/8

f)1,5:1/2=1 5/10:1/2=15/10*2/1=15/5=3

g)2,125:1/8=2,125/100:1,8=325/100*8/1=2600/100=26

h)0,5:1/4=1/2:1/4+1/2*4/1=2

 

 

a)1/5*1/8=1/40

b)1 1/3*2 7/10=4/3*27/10=36/10=3,6

c)=4/3*15/4*1/5=1

d)0,75:0,0375=20

e)0,48:1,14=0,42

f)=(24/11*3/8)*0,11=9/11*0,11=0,81*0,11=0,0891

h)18/10:(4/3*27/4)=18/10*1/9=2/10=1/5
