<span>The central number in a geometric progression (e.g., 9 in 3, 9, 27 ), also calculable as the n the root of a product of n numbers.

Answer:
find the lcm (least common multiple) of the three denominators
The parenthesis should be placed in 310-20/2 x (5 + 13) =130
It would be 2 2/25, so it would be d.
1 3/8 the denominators have to be the same so you multiply 2 to 3/4 to get 6/8 btw they are common denominators so you can easily multiply two and the you add the to get 11/8 and if you simplify it you'll get 1 3/8
