To convert decimals to fractions. place the decimals over '1. 0000'. The number of 'zeroes' is the same as the number of decimal places above. Hence 0.3175/1.0000 Cancel down the decimal point 03175/10000 The 'zero' in theh numerator is trivial and can be discounted. Hence 3175/10000 Since both number end in '5' and/or '0' they will cancel down by '5'. Hence 635/2000 Repeat by '5' again. 127/400 This will not cancel down any further. NB For decimals recurring to infinity there is a different technique. For irrational decimals , such as 'pi' , cannot be converted to a fraction.
There cannot be a whole fraction. If it is a fraction it is not whole and if it is whole it is not a fraction.
No, every fraction is not a unit fraction because unit fraction must have 1 as numerator but every unit fraction is a fraction such as 2/3 is a fraction but not considered a unit fraction and 1/3 which is a unit fraction is also called fraction
Improper fraction is greater than a proper fraction.
That's a complex fraction.
