Question

Hi there, please help me with answering this question. I am a bit confused here. Please help me answer for the lower sum. I attempted but it seems that my answer was incorrect or just a bit off. For reference, the incorrect answer was 40/27. Please read the question carefully because sometimes my questions are answered incorrectly and unfortunately I do not receive a refund for them. Please answer with legible handwriting as well. Thank you very much. Thumbs up always given for well explained answers!
