Answer:
Sophi e checks her bike for repairs every 9 days and Susan checks hers every 12 days. after 36 days they next both check their bike.
Step-by-step explanation:
Sophie checks her bike for repairs ever 9 days .
Susan checks her bike for repairs every 12 days.
L.C.M of 9,12
9 = 3 * 3
12 = 2 * 2 * 3
LCM = 3 * 3 * 2 * 2 = 36
therefore LCM of 9 ,13 = 36
After 36 days next Sophie and Susan check their bike.
Least Common Multiple i.e. LCM is to find the minimum common multiple between two or more numbers. LCM denotes the least value of common factor or multiple of any two integers.
The concept of L.C.M. is important to solve problems related to racetracks, traffic lights, etc.
