4% din 27 = 4×27÷100=108:100=1,08

27%din 4 =27×4÷100=108÷100=1,08

1,08-1,08=0

ex 12

20% /100×X=4

x/5=4

x=5×4

x=20

20-4=16

ex 13

100%... X

30%.....30000

100/30=x/30000

x=( 100×30000)/30

x= 3000000/30

x= 100000

ex 14

100%....X

20%.....50000

100/20=x /50000

x= (100×50000)/20

x= 5000000/20

x=2500000
