Answer:
a = 11/12
Explanation:
Start by isolating "a" by subtracting 1/3 from the left and right sides.
a = 5/4 - 1/3
In order to combine the fractions, we need to find the lowest common denominator. That means the lowest number that is divisible by both 4 and 3. In this case, the lowest common denominator is 12.
So 5/4 becomes 15/12 and 1/3 becomes 4/12. 15/12 - 4/12 = 11/12
a = 11/12
