Converting Decimal to Vulgar Fraction:
0.25 = 25/100
After the dot, how many digits are there?
Two digits after the decimal point, so in the denominator 1 followed by two zeros.
Remove the decimal point and place the number in the numerator.
After removing the decimal point, we have 25. so numerator = 25.
Denominator = 100 because two digits after the decimal, so 100.
Example 2:
2.008 = 2008/1000 = 251/125.
Example 3:
1.84/2.99 = 184/299 = 8/13
Maintain the same number of digits after the decimal point and remove the decimal point.
1.84/2.99 = 0.6153
8/13 = 0.6153
Example 4:
1.8/2.99 = 1.80/2.99
adding zero after eight will not change the value.
180/299
