Answer: 140

Step-by-step explanation:

Given : The rabbit population in a certain area 500% of last year's population. There are 700 rabbits this year.

Let x be the number of rabbits in last year.

Then , According to the question , we have

500% of x = 700

[tex]\Rightarrow\ \dfrac{500}{100}\times x=700[/tex]  [To convert percent into fractions , we divide it by 100]

[tex]\\\\\Rightarrow\ 5\times x=700\\\\\Rightarrow\ x=\dfrac{700}{5}=140[/tex]

Hence, there were 140 rabbits last year.
