Problema Solution
There are two bells in the school. Bell A rings every 2 minutes. Bell B rings every 3 minutes. If both bells ring together at 8.02 p.m., when will they ring together again?
Answer provided by our tutors
Bell A rings 1/2, Bell B rings 1/3 and then find the least common denominator of those fractions:
1/6
So every 6 minutes those bells will ring together, hence as 8:08 p.m.
