Solution:
<u>Note that:</u>
- 1 min = 60 sec
- 1 h = 60 min.
<em>The given time is in seconds. Convert it into minutes by dividing it by 60.</em>
- => 25,200 seconds = 25,200 ÷ 60 minutes = 420 minutes
<em>The obtained time is in minutes. Convert it into hours by dividing it by 60.</em>
- => 420 minutes = 420 ÷ 60 hours = 7 hours
<u>We can conclude that:</u>
- 25,200 seconds = 420 minutes = 7 hours

Answer: (2.75-2.40)/(2.75) * 100 [Before rounding to the nearest tenth]
Step-by-step explanation:
Formula for percentage decrease = (old-new)/(old) * 100
so substituting in, you get (2.75-2.40)/(2.75) * 100
From here, you can just plug this into a calculator (don't have on me rn)
Yes.
A fraction means that you divide the top number (numerator) by the bottom number (denominator). So, if you divide 4 by 16, then the answer is 0.25
Another way to get this answer is if you know your basic fraction-decimal conversions. If you reduce the fraction by dividing both the numerator and the denominator by the same number (in this case, 4 works), then you get the fraction 1/4, which is also equal to 0.25
Good luck with your math, and I hope this helps :)
