Answer 1

5/24

Explanation:

In her career Erika carries out three diff types of responsibility: filing, typing and tending the phones. Adding 1/6 to 5/8 and subtracting the sum from 1 will result in the fraction of her time that she answers the phone:

1 - (1/6 + 5/8)

Here the LCD is 24, so this expression becomes

1 - (4/24 + 15/24), or

1 - 19/24

= 5/24

Ericka spends 5/24 of her career answering phones.
