a class has LESS THAN 30 students we must find what number is less than 30 and divides into both 4 and 8 so that we don't have a fraction of a student owning a football boot the class could have 8 students the class could have 16 students the class could have 24 students lets assume that the class has the max possible so 24 in the class
so we must find a coommon denomenator (bottom number) to keep the fractions the same we must multiply it by 1 or (number)/(same number as on top) or 1/1 so 3/4 times 2/2=6/8 7/8 so we must assume that the ones who own footballs also have boots (and not some other random person) so 6/8 or 3/4 of the class owns both football boots so 3/4 times 24=18 18 students own football boots
