Lamont surveyed his class on how they spent their free time during the week

2 is the number of hours using electronic devices :

1 hours playing sports

Also known as 2:1

Step-by-step explanation:

The first step is to simplify the ratio of hours using electronic devices to hours playing sports, which is 30 : 15

30 : 15

If I divide each number by 5 to simplify you get:

6 : 3

Then we divide each number by 2 to simplify:

2 : 1

That is how you get the answer for the ratio of 2:1.

I hope I helped and have a great day! ^-^
