Answer 1

Answer:

There are 80 teddy bears in the store.

Step-by-step explanation:

Let the ratio of the number of dolls to the number of teddy bears is 9:3.

Total no of dolls = 240

We need to find the no of teddy bears in the store.

Let D and T are the no of dolls to the no of teddy bears.

So,

$\dfrac{D}{T}=\dfrac{9}{3}\\\\T=\dfrac{3D}{9}\\\\\text{Put D= 240}\\\\T=\dfrac{3\times 240}{9}\\\\T=80$

So, there are 80 teddy bears in the store.
