Mr. Smith's wife works at an animal hospital. There is a equivalent fraction relationship between the number of dogs and cats in
dimulka [17.4K]

Answer:

There are 10 dogs in the kennels

Step-by-step explanation:

The equivalent fraction relationship between the number of dogs and cats in the kennels is 1/2.

Which means, if n_d the number of dods and n_c is the number of cats, then,

\frac {n_d}{n_c}=\frac{1}{2}\cdots(i)

Given that there are 20 cats, so n_c=20.

Now, from equation (i) we have,

\frac {n_d}{20}=\frac{1}{2}

\Rightarrow n_d=\frac{1}{2}\times 20

\Rightarrow n_d= 10.

Hence, there are 10 dogs in the kennels.

Answer:

option a) 30 : 19

Step-by-step explanation:

Length = 7 \frac{1}{2} = \frac{15}{2}\\\\Width = 4\frac{3}{4} = \frac{19}{4}

<em><u>Ratio of length to width:</u></em>

      \frac{15}{2} : \frac{19}{4}<em><u></u></em>

    =\frac{\frac{15}{2}}{\frac{19}{4}}\\\\=\frac{15}{2 } \times \frac{4}{19}\\\\=15\times \frac{2}{19}\\\\=\frac{30}{19}\\\\30 : 19
