Hi guys i know this might be the incorrect section to post this but it is work related.hopefully somebody can help basicly im rubbish with numbers and what i want to know is:
If 8hours is 100%
How many minutes are there to 1%?

Thankyou in advance

8*60= 480

1/100*480= 4.8

0.8*60= 48

4.8 minutes or 4 minutes and 48 seconds by my calculations.

4 mins 48 seconds ..I think

Thankyou guys,this is also what i got but then i confised myself.
So if 4.48minutes is 1%
What would be 5% and 10% in minutes also?
I have really confused myself i think i have thought about this too hard

D4nny

Well accordingly 45mins20secs should be 10%?

No! 10% of 8 hours is .1 x (8 x 60) = 48 minutes.

If you ask at your local college or library they can offer assistance with basic numeracy.

It's not 4.48 minutes, it's 4 minutes and 48 seconds, which is 4 and 48/60 minutes or 4.8 (4 and 80/100 minutes). Hope that helps.

No, previous posters said it was 4.8 mins, which is also 4m48s, NOT 4.48mins

Assuming 4.8 and 4m48s to be correct;

5 * 4.8 = 24 mins
(5*4) + (5*48 / 60) = 20 + 4 = 24mins

10% is double 5%, so 24*2 = 48mins

If you don't follow the method, just ask.


To expand on Southend1's post;

8h*60(mins)*60(secs) = 28800 seconds in 8 hours

1% or 1/100th of 28800 = 288 (seconds)

288 / 60 = 4(mins) leaving 48 seconds (4*60 = 240. 288 minus 240 = 48), so

1% = 4mins 48secs

Or, starting with finding 10% rather than 1% :

10% of 8 hours is one-tenth of 8 hours which is eight-tenths of one hour.

An hour is sixty minutes and a tenth of sixty minutes is six minutes. So eight-tenths of one hour is eight times six minutes. 8x 6 is 48.

That is 10% and 5% are 48 and 24 minutes (as above.)

Another alternative is to start by converting and working with minutes.

That is, eight hours is 480 minutes. You can then find a tenth or twentieth or hundredth of that (probably) straightforwardly.
