AboutJohn Zalewski Expertise I can help you solve problems involving fractions, decimals, ratios, and algebra. I can teach you how to do math faster, and even in your head. I can teach math definitions, and help you study, if necessary. Please do not ask any graphing, trigonometry, or calculus questions. Try to work through homework questions before asking for assistance.
Experience I routinely process numbers of all kinds in my head, without need of a calculator.
Education/Credentials I was an A math student while in high school.
I've had such a torturous time with fractions and decimals throughout my life. Math has never been my strong suit.
At work, I have to put down the hours employees work. If they work 8 hours then obviously, I put down 8. If they're a half hour late, I'll put 7 1/2. But I've never been completely sure what I should put down if they come 15 minutes late or 45 minutes late. Does that appear as 7 3/4 for example?
Thank you for your time.
David.
Answer Hello, David.
Since there are 60 minutes in an hour, if an employee shows up 15 minutes late, then they are present for 45 minutes of the hour.
45 minutes / 60 minutes/hour = 3/4 hour (divide both sides of the fraction by 15).
Therefore, if an employee is 15 minutes late, write in 7 3/4.
If an employee is 45 minutes late, they are present for 15 min/60 min/hour, or 1/4 hour.
