A survey was done that asked students to indicate whether or not they have ever prepared a meal for their family.What is the ratio of those who have prepared a meal for their family to those who have not?Enter your answer, in simplified form without decimals, in the boxes.

The ratio is 17 to 16.

First, you need to add up all the yes votes. 
23 + 147 = 170

Second, you need to add up all the no votes.
112 + 48 =160

So our ratios is 170:160.
You can divide this by 10 to get a simplified ratio of 17:16.
