The value of 3a² is 27.
Step-by-step explanation:
Rule: The sum of any integer and its opposite is equal to zero. Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.
First, we want the denominators to be the same. To do this, we can multiply the numerator and the denominator in the second fraction by 9.
11/36-9/36= 2/36
2/36= 1/18
Final answer: 1/18
