Time is not on my side!!!

P: 53
Ok, here is my query quandry

This may be more of a math question but I need help anyway. I should have paid attentionin high school i guess

I have a large amount of data that that is entered each day into a database. Two peices of the data need to be divided by each other to arrive at a percentage. Both types of data are time. However both come to me in a different format.

Here is an example of how they come:
[Time1] comes as a decimal format. 8.17 hours is 490.2 minutes or 8 hours 10 minutes.

[Time2] comes as a hour:minute format. 1:11 is 71 minutes or 1 hour 11 minutes.

The math that needs to take place is [time2]/[time1] which in this case would be 14.5%

Question 1: What should the field types of my data be in the table for both?
Question 2: How do I convert one or both to the right number types in a equation to get the right percentage?

Obviously I could have the people who enter the data do exactly what I did above, however its a large amount of data on a daily basis and would not be productive to do so. I also want to eliminate human error as much as possible.

Any help and suggestions offered would be highly appreciated

What you want is to turn these values into minutes in order to calculate the percent.

Obviously Time1 is a number and not time type.

So in your query create 3 new fields like this:
