Question

If it takes 4 years for an animal population to double, how many years will it take until the population triples?

Answer 1

Answer:

6 years

Step-by-step explanation:

i used a proportional approach

2 (the double)/ 4 years (the time it takes to double)

then compared it to

3(the triple)/ x amount of years

(like this)

$\frac{2}{4} \ \frac{3}{x}$

then cross multipled

4 times 3= 12

then divided the 12 by the remaining 2 above the 4
