Answer:

28.1%

Step-by-step explanation:

Population increased by (561000-438000)=123000

rate of increase

= (123000/438000)*100

=28.08

=28.1

The answer is 78.1

The equation is part/whole = %/100
And if you plug numbers into that it would be 438000/561000 = x/100
Cross multiply leaving you with 43,800,000 = 561000x then divide them
43,800,000/561000 = 78.07 or 78.1
