To subtract -3/16 from -1/20 and express the result in simplest fraction form, you need to find a common denominator for the two fractions. In this case, the common denominator is 80 because it's the least common multiple of 16 and 20. Here's how to do it step by step:

1. Rewrite both fractions with a common denominator of 80:
-3/16 = -15/80 (Multiply the numerator and denominator of -3/16 by 5)
-1/20 = -4/80 (Multiply the numerator and denominator of -1/20 by 4)

2. Now that both fractions have a common denominator, you can subtract them:
(-15/80) - (-4/80) = (-15/80) + (4/80)

3. Add the fractions together:
(-15/80) + (4/80) = (-15 + 4)/80 = -11/80

So, the result of subtracting -3/16 from -1/20 in simplest fraction form is -11/80.
