Answer:
Li Jing's formula i.e. 
is right.
Step-by-step explanation:
Considering the sequence
A geometric sequence has a constant ratio r and is defined by
So, the sequence is geometric.
as
so
Therefore, Li Jing's formula i.e. is right.
First find the least common denominator (8), and then subtract. After subtracting you should get 31/8, which as a decimal is 3.875 and as a mixed number is 3 7/8.
Answer:
0.75 is the answer
Step-by-step explanation:
6/8 is equivalent to 3/4
3 divided by 4 is 0.75
Since 6/8 is equivalent then it is also 0.75
Also 6/8 turn to 3/4 when both the numerator and denominator is divided by 2.
6 divided by 2 is 3
8 divided by 2 is 4
