How do I add time?

If a person worked 4 1/2 hours on Monday, 4 1/2 hours on Tuesday and 2 hours on Wednesday, does that add up to 12 hours? If not, how much more time would the person need to work the next day to equal 12 hours?

add them!!

adding it comes 11 hrs

subtract 11 from 12

okay thx

To add time, you simply need to add up the hours worked on different days. Let's go step by step to calculate the total hours worked in this case:

1. The person worked for 4 1/2 hours on Monday.
- To add this time, convert the fraction into a decimal. 1/2 is the same as 0.5, so the person worked for 4 + 0.5 = 4.5 hours on Monday.

2. The person worked for 4 1/2 hours on Tuesday.
- Similar to before, convert the fraction into a decimal. 1/2 is equal to 0.5, so the person worked for 4 + 0.5 = 4.5 hours on Tuesday.

3. The person worked for 2 hours on Wednesday.

To find the total hours worked, add up the hours worked on each day: 4.5 + 4.5 + 2 = 11 hours.

So, the person worked a total of 11 hours over the three days, not 12.

To determine how much more time the person would need to work the next day to equal 12 hours, subtract the total hours worked (11) from the desired total hours (12):
12 - 11 = 1 hour.

Therefore, the person would need to work an additional 1 hour on the next day to reach a total of 12 hours.
