Question

oblicz 2/3 * 7,2= 1i4/5:0,25= 1/3 *7,2= 3 i 4/5:0,25= 1/9 * 6,3= 1 i 2/5 :0,25= 2/9*6,3= 2 i 2/5:0,25=

Answer 1

2/3 * 7,2=2/3*72/10=144/30=4,8 

1i4/5:0,25=9/5*100/25=900/125=7,2 

1/3 *7,2=1/3*72/10=72/30=2,4 

3 i 4/5:0,25=19/5*4= 76/5=15,2

1/9 * 6,3=1/9*63/10=63/90=21/30=7/10=0,7 

1 i 2/5 :0,25=7/5*4=28/5=5,6 

2/9*6,3=2/9*63/10=126/90=1,4 

2 i 2/5:0,25=12/5*4=48/5=9,6

Answer 2

2/3 * 7,2 = 2/3 * 72/10 = 1/1 * 24/15 = 24/ 5 = 4 i 4/5

 

1i4/5 : 0,25 = 9/5 : 1/4 = 9/5 * 4/1 = 36/5 = 7i1/5

 

1/3 * 7,2 = 1/3 * 72/10 = 1/1 * 24/10 = 24/10 = 2i4/10 =2i2/5

 

3 i4/5 : 0,25 = 3,8 : 0,25 = 15,2

3i4/5 : 0,25 = 19/5 : 1/4 = 19/5 * 4/1 = 76/5 = 15i1/5

 

1/9 * 6,3 = 1/9 * 63/10 = 63/90 

 

1i2/5 : 0,25 = 7/5 : 1/4 = 7/5 * 4/1 = 28/5 = 5i3/5

1i2/5 : 0,25 = 1,4 : 0,25 = 5,6

 

2/9 *6,3 = 2/9 * 63/10 = 126/90= 1 i 36/90= 1i 4/10= 1 i 2/5

 

2i2/5 : 0,25 = 12/5 : 1/4  = 12/5 * 4/1 = 48/5 = 9 i 3/5

2i2/5 : 0,25 = 2,4 : 0,25 = 9,6
