Answer:
[tex]\frac{9}{20}[/tex]
Step-by-step explanation:
Let total number of crates be x
Since we are given that An animal shelter has [tex]\frac{9}{10}[/tex] of its crates filled with animals
So, crates filled with animals = [tex]\frac{9}{10}x[/tex]
Now we are also given that [tex]\frac{1}{2}[/tex] of the filled crates are holding dogs .
So, fraction of the total number of crates are holding dogs:
[tex]\Rightarrow\frac{1}{2} \times \frac{9}{10}x[/tex]
[tex]\Rightarrow\frac{9}{20}x[/tex]
Hence [tex]\frac{9}{20}[/tex] of the total number of crates are holding dogs .
