Every number is being divided by 1
0.055=‌

0.055

1

Count how many times you have to move the decimal point to obtain a whole number.
In 0.055, we have to move three (3) times.
Multiply both the decimal and 1 by 1nOs
Where nOs means number of zeros which is the number of times you have to move the decimal point to obtain a whole number.
In 0.055 we have to multiply both 0.055 and 1 by 1000 , three (3) zeros after the 1 (1000).
Multiplying the decimal by 1000 makes it a whole number.
Simplify the numerator and the denominator.
