Your question is not clear, if you are asking: what is \(63 \frac{12}{60}\) simplified? Then the answer is \(63 \frac{1}{5}\) or \(63.2\).
If 63 is just the question number and you are asking, what is \(\frac{12}{60}\) simplified. Then the answer is \(\frac{1}{5}\) or \(0.2\)
You get this answer by finding the highest number that both the numerator and denominator are divisible by, and diving both numbers by that:
\(\frac{12}{60} \div \frac{12}{12} = \frac{12 \div 12}{ 60 \div 12} = \frac{1}{5} = 0.2\)
