Question

An animal shelter has 9/10 of its crates filled with animals. 1/2 if the filled crates are holding dogs. What fraction of the total number of crates are holding dogs?

Answer 1

Answer:

$\frac{9}{20}$

Step-by-step explanation:

Let total number of crates be x

Since we are given that An animal shelter has $\frac{9}{10}$ of its crates filled with animals

So, crates filled with animals = $\frac{9}{10}x$

Now we are also given that $\frac{1}{2}$ of the filled crates are holding dogs .

So, fraction of the total number of crates are holding dogs:

$\Rightarrow\frac{1}{2} \times \frac{9}{10}x$

$\Rightarrow\frac{9}{20}x$

Hence $\frac{9}{20}$ of the total number of crates are holding dogs .

Answer 2

4/10 or 2/5 because 1/2 is 5/10 and 9/10-5/10=4/10
