Answer:
B
Step-by-step explanation:
to simplify a fraction, divide numerator/ denominator by the largest common factor, often called cancelling
the largest common factor of 36 and 84 is 12
[tex]\frac{36}{84}[/tex] = [tex]\frac{3}{7}[/tex] ← in simplest form
A fraction is in simplest form ( lowest terms ) when no factor but 1 divides into the numerator/ denominator.
