The answer is 8/12 because you find a common denominator which is 12 so if you multiply 4×3 on the bottom you do it to the top which gives you 3 so 11-3 is 8. 11/12 - 3/12

Answer: 35
Step-by-step explanation:
The average can be found by adding their ages together and dividing by the number of ages.
Given:
= 23
Multiply both sides of the equation by 5:
19 + 20 + 20 + 21 + x = 115
Combine like terms:
80 + x = 115
Subtract 80 from both sides of the equation:
x = 35
Erica is 35.
