Answer:

[tex]\frac{4}{21}[/tex]

Step-by-step explanation:

When simplifying fractions, you need to find the biggest common factor between the numerator (12) and denominator (63). In this case, the biggest common factor is 3.

Thus:

Numerator = 12 ÷ 3

                  = 4

Denominator = 63 ÷ 3

                      = 21

[tex]\frac{12}{63}[/tex] = [tex]\frac{4}{21}[/tex]
