Multiples that are shared by two or more numbers are COMMON MULTIPLES.
The least common multiple (LCM) is the smallest common multiple of two numbers, other than 0.
multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30
multiples of 6: 6, 12, 18, 24,30,36,42,48,54, 60
the common multiples of 3 and 6 are 6, 12, 18, 30
the least common multiple of 3 and 6 is 6.
There are 100 possibilities for the last two digits [ if we include
00].....therefore....you have 1/100 chance [1 % ] chance of
choosing the correct one.....
A) -4
d) -3.1
for these questions you have to subtract the two numbers since they have different signs and the biggest sign is the ending sign
