What is the value of x on number 3?

So if the denominator of the problem on the left of the equal sign is 4 that means the numerator has to equal to 2 because 2/4 simplified is 1/2. To get 2 on the top you need to see what times 3 equils 2 which is .66 repeated. Then x would equip 8.66 repeated

The ratio of dogs to the total number of animals is simply 16 to 22+16+4=42. So our answer is 16:42
