The lcd of two fractions is always greater than the denominator of the fractions. Reasonable or not?
2 answers:
Lcd means least common denomenators it is normally used to combine fractions with differnt denomenators I can show 2 disproofs so they can be equal conside 3/4 and 5/8 lcd is 8, 8>8 is false not reasnable they can be less if they arenot simplified example 4/8 and 24/16 lcd is 4 not reasonable
It is not reasonable. The LCD can be less than the denominators if the fractions are not in simplest form but the LCD can be equal to one of the fractions even if they are in simplest form, for example: 3/4 and 1/2 Hope this helps :)
