There are 50 animals in a shelter. Sixty percent of the animals are dogs. Which equation can be used to find the number of dogs in the shelter? $\frac{60+2}{100+2}=\frac{30}{50}$ $\frac{100 \times 2}{50 \times 2}=\frac{200}{100}$ $\frac{50+1}{60+1}=\frac{50}{60}$ $\frac{60 \times 2}{50 \times 2}=\frac{120}{100}$ Mark this and return Save and Exit Next

Step 1 ：The question is asking for the equation that can be used to find the number of dogs in the shelter. Given that there are 50 animals in total and 60% of them are dogs, we can represent this situation with the equation \(\frac{60}{100} = \frac{x}{50}\), where x is the number of dogs.

Step 2 ：Looking at the provided options, the equation that matches this format is \(\frac{60 \times 2}{50 \times 2}=\frac{120}{100}\), because it can be simplified to \(\frac{60}{100} = \frac{x}{50}\).

Step 3 ：Final Answer: The equation that can be used to find the number of dogs in the shelter is \(\boxed{\frac{60 \times 2}{50 \times 2}=\frac{120}{100}}\).
