Step-by-Step Solution

Let's write the exercise as a fraction:

3m×12n7m×4n= \frac{3m\times12n}{7m\times4n}=

Let's reduce between the m in the numerator and the n in the denominator:

3×127×4= \frac{3\times12}{7\times4}=

Let's write the 12 in the numerator of the fraction as a smaller multiplication exercise:

3×4×37×4= \frac{3\times4\times3}{7\times4}=

Let's reduce between the 4 in the numerator and the denominator:

3×37=97=127 \frac{3\times3}{7}=\frac{9}{7}=1\frac{2}{7}

Answer

127 1\frac{2}{7}
