City A is 25% less than population of city B. So city A's population is 75% of city B
Solution:
Given that City A is 25% less than population of city B
To find: city A's population is what % of city B
From given information,
City A is 25% less than population of city B
A = B - 25% of B
So we can write as,
![A = B - (25)/(100) * B\\\\A = B - 0.25B\\\\A = 0.75B](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mm83hfzbd3u12360396klcfttijldrq8hc.png)
A = 0.75B can be written as,
![A = (75)/(100)* B](https://img.qammunity.org/2020/formulas/mathematics/middle-school/3e0barqt27bce5p49cpu1bi8lut9c1jh2v.png)
city A = 75 % of City B
Thus city A's population is 75% of city B
