If a phone charges 3% every five minutes then how long will it take for the phone to charge 100%
postnew [5]

To find out how long it will take a phone to charge 100% if it charges 3% every 5 minutes, you have to put it in a fraction.

3/5

3 is the percent charged and 5 is the time.

You have to find out what 100 divided by 3 is. The answer is 33.3.

So,

3/5 times 33.3 is equal to 99.9/166.5.

It will take 166.5 minutes for the phone to charge to about 100%.

hope it helps.

can you choose mine as the brainliest answer

Solve the Equation p+5/8=15/16?
Sphinxa [80]
So the first thing you want to do when faced with two fractions with different denominators (when subtracting or adding) is to make the denominators the same. So for this equation they would turn out to be p+10/16=15/16 (because 16 is the lowest common denominator, 8 times two) so then you want to subtract 10/16 from 15/16 to isolate the variable (p) which would get: 
p=5/16
This is the final answer because it cannot be simplified.
Hope this helps!
