Rewrite as multiplication: Rewrite the division as a multiplication by taking the reciprocal of the divisor. So, (12n/14m)÷(4m2n) becomes (12n/14m)×(1/(4m2n)).
Multiply numerators and denominators: Multiply the numerators and then multiply the denominators. So, (14m12n)×(4m2n1)=14m×4m2n12n×1.
Simplify by canceling factors: Simplify the expression by multiplying the denominators and canceling out common factors. The numerator is 12n and the denominator is 56m3n. We can cancel out the common factor of n from the numerator and denominator, and also divide both the numerator and the denominator by 4, which is a common factor.
Final simplified expression: After simplification, the expression becomes (5612)×(m31)=(143)×(m31)=14m33.
