Answer:
5/12
Explanation:
Let's assume the salesperson's pay for the week is represented by the variable "P."
According to the given information:
She earns 1/3 of her pay on Monday, which is (1/3) * P.
She earns 1/4 of her pay on Tuesday, which is (1/4) * P.
To find out how much she earns on Wednesday, we need to determine the remaining portion of her pay for the week after Monday and Tuesday:
Remaining pay = Total pay - Monday's pay - Tuesday's pay
Remaining pay = P - (1/3) * P - (1/4) * P
Now, we need to find a common denominator for 3 and 4, which is 12:
Remaining pay = P - (4/12) * P - (3/12) * P
Remaining pay = P - (4/12 + 3/12) * P
Remaining pay = P - (7/12) * P
Now, let's calculate the pay she earns on Wednesday:
Wednesday's pay = Remaining pay = (1 - 7/12) * P
Wednesday's pay = (5/12) * P
So, the salesperson earns 5/12 of her pay on Wednesday.
