Answer:
One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

Answer:
Step-by-step explanation:
Given expression is 
.
Now we need to multiply this using FOIL.
F = First 
O = Outside 
I = Inside 
L = Last 
Hence we get :
Answer:
22/7 * 8.5 * 8.5 = answer
Note that there's a strict order here -> 2 close friends, then 1 non-close friend.
So, picking in order:
probability of picking the first close friend: 4/10
probability of picking the second close friend: 3/9
probability of picking the first non-close friend: 6/8
So, we get 4/10 * 3/9 * 6/8 = 1/10.
