Step-by-step explanation:

percentages as a ratio:

i-19% ii- 36% iii- 12.5% iv- 27% v- 130% ​

Percentage is a number

It is a fraction of 100

Replace % by fraction of 100

Ratio is a relationship between two quantities

It shows that how many times one number contains another

i)19%=19/100

19/100=19:100

ii)36%=36/100

36/100=9/25

9/25=9:25

iii12.5%=12.5/100

  12.5/100=2.5/20

 Multiply 10 in the numerator and the denominator to remove decimal point

  2.5/20=25/200

  25/200=5/40

  5/40=1/8

  1/8=1:8

iv)27%=27/100

   27/100=27:100

v)130%=130/100

  13/10=13:10
