0.07 is 7/100 in its lowest terms.
this is because 7 and 100 do not have any common factor therefore they can not be reduced any further.
for example there is a number 24.02
which is 2402/100 as a fraction but here 2402 and 100 have a common factor (=2) so we can cancel 2 from both numerator and denominator and we have 1201/50 because 1201*2 = 2402, 50*2=100.
therefore 1201/50 is the lowest fractional form of 24.02 because now 1201 and 50 do not have any common factor to get reduced any further. :) happy learning!
