You need to find the lowest common multiple for 21, 147, and 588 It is 588, so this will be the common denominator.... 21 goes into 588 28 times 147 goes into 588 4 times So we re-write the fractions as: (2x28 / 588), (4x4 / 588), (3x4 / 588) and (5 / 588)

Hi thank you so much! I am just lost on how we GET the number 588 as the LCD :( haven't had math in 10 years and I'm afraid the "easy" stuff has me lost.
