There us 120 students in the 5th grade 50% of them have a dog, how many 5th grader have a dog?

Hello!

First you have to convert the decimal into a percent

50% = 0.50

Multiply this by the amount of students.

120 * 0.50 = 60

The answer is 60

Hope this helps!

Hi there!

In order to solve this problem, we'll need to set up a proportion. The proportion we are going to use is x/120 = 50/100. Next, we'll cross-multiply, giving us 100x = 6000. Lastly, we'll divide each side by 100, giving us 60 5th graders that have a dog.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
