Answer 1

Answer: 60%

Explanation:

Take the two top numbers which is [5x] and [25y], see how many times 5 go into number 25. In this case it's 5 times, you then go the height of the Television [12y] and [4x]. You take your answer from the length which is [5] and multiply by the height which is [4x]. That will become 20, then you do 12y ÷ 20 = 0.60

Your answer is c. 60%
