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