Let's represent our number as x.
x is being added to 6 * x², and it equals 12

Factor:

Solve for x:

Therefore,
x = -3/2 and 4/3.
To find the fraction inbetween,
1. Add up the 2 fractions
2 Divide it by 2
Step (!) Add them up:
2/3 + 1 1/3 = 2
Step (2) Divide the answer by 2:
2÷ 2 = 1
Answer: The number between 2/3 and 1 1/3 is 1.
Answer:
π/3
Step-by-step explanation:
We have to find the principal value of 
arc sin means sin inverse. The sin inverse is a one to one function with its range between 
The principal value of the arc sin will lie within the above given range.
value of sin (60) or sin(
) is
.
lies between 
So, from here we can say that the Principal Value of Arc sin(square root of 3/2) is π/3
