What is 1 2 1 4 as a fraction in simplest form?
This question requires a bit of clarification. "1 2 1 4" could be interpreted in a few ways:
1. A mixed number:
If you mean the mixed number 1 2/14, then we can follow these steps to simplify:

Convert to an improper fraction: Multiply the whole number (1) by the denominator (14), and add the numerator (2). This gives us 16. Keep the same denominator. (1 * 14) + 2 = 16
Therefore, the improper fraction is 16/14. 
Simplify: Find the greatest common factor (GCD) of 16 and 14, which is 2. Divide both numerator and denominator by 2. 16 / 2 = 8 14 / 2 = 7 This gives us 8/7 as the simplified fraction.
2. A sequence of numbers:
