Answer:
B = 1320
![A= \dfrac54B](https://tex.z-dn.net/?f=A%3D%20%5Cdfrac54B)
Step-by-step explanation:
Let A = number of students at Branch A
Let B = number of students at Branch B
If the number of students taking classes at Branch A is 1/4 more than Branch B, then:
![A=1 \dfrac14B](https://tex.z-dn.net/?f=A%3D1%20%5Cdfrac14B)
![\implies A= \dfrac54B](https://tex.z-dn.net/?f=%5Cimplies%20A%3D%20%5Cdfrac54B)
If Branch A has 1,650 students, then substitute A = 1650 and solve for B:
![\implies 1650= \dfrac54B](https://tex.z-dn.net/?f=%5Cimplies%201650%3D%20%5Cdfrac54B)
![\implies 1650 \times 4= 5B](https://tex.z-dn.net/?f=%5Cimplies%201650%20%5Ctimes%204%3D%205B)
![\implies 6600 =5B](https://tex.z-dn.net/?f=%5Cimplies%206600%20%3D5B)
![\implies B=\dfrac{6600}{5}](https://tex.z-dn.net/?f=%5Cimplies%20B%3D%5Cdfrac%7B6600%7D%7B5%7D)
![\implies B=1320](https://tex.z-dn.net/?f=%5Cimplies%20B%3D1320)
