If John has p hours of homework and has worked for r hours, what part of his homework is yetc to be done?
Solution:(p-r)/p or1-r/p
am I correct?
Yes, you are correct! The part of John's homework that is yet to be done can be calculated using the formula (p - r)/p or 1 - r/p. This formula represents the remaining hours of homework (p - r) divided by the total hours of homework (p). This will give you a decimal value that indicates the proportion of the homework that is yet to be done.
Yes, you are correct. The part of John's homework yet to be done can be calculated using the formula (p - r)/p or 1 - r/p.
To explain further, let's break down the formula:
p represents the total hours of homework that John has.
r represents the hours John has already worked on his homework.
To find the part of his homework yet to be done, we need to subtract the hours he has worked (r) from the total hours of homework (p). This gives us (p - r), which represents the remaining hours of homework.
To express the remaining hours as a fraction of the total hours of homework, we divide the remaining hours (p - r) by the total hours (p). This gives us (p - r)/p.
Alternatively, we can express the remaining hours as a percentage of the total hours. To do this, we divide the worked hours (r) by the total hours (p) and subtract it from 1. This gives us 1 - r/p.
Both (p - r)/p and 1 - r/p are valid ways to represent the part of John's homework yet to be done.
I don't think so. Put this is numbers as in the problem with x and y dollars.
John has homework= p
He has worked=r
R/p
