Question

Rabbit population: the rabbit population in a certain area 500% of last year's population. There are 700 rabbits this year. How many were there last year?

Answer 1

Answer: 140

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

`\Rightarrow\ (500)/(100)* x=700` [To convert percent into fractions , we divide it by 100]

`\\\\\Rightarrow\ 5* x=700\\\\\Rightarrow\ x=(700)/(5)=140`

Hence, there were 140 rabbits last year.
