Answer:

$1\frac{1}{3}$

Step-by-step explanation:

Given the following question:

$4\times\frac{1}{3}$

To find the answer simply multiply the numerators and the denominators by each other.

$4\times\frac{1}{3}$
$4=\frac{4}{1}$
$\frac{4}{1} \times\frac{1}{3}$
$4\times1=4$
$1\times3=3$
$=\frac{4}{3}$
$\frac{4}{3} =4\div3=1\frac{1}{3}$
$1\frac{1}{3}$

Hope this helps.

Phantasy [73]

Answer:

Step-by-step explanation:

If that number is greater than 1, that means that the exponential equation represents growth. If that number is less than 1 but greater than 0, that means that the exponential equation represents decay. Since ours is greater than 1, our equation is exponential growth. It means that the perent of animals adopted grows at a rate of 145% per year, with a starting number of 28 animals in the first year.
