Step-by-step solution

The problem asks us to simplify the expression 14a2a3a\frac{14a}{2a \cdot 3a}.

First, simplify the expression in the denominator:

  • The denominator 2a3a2a \cdot 3a can be expanded by multiplying the constants and variables separately: 23aa=6a22 \cdot 3 \cdot a \cdot a = 6a^2.

Now, the expression becomes:

  • 14a6a2\frac{14a}{6a^2}

Next, simplify the fraction by canceling out common factors in the numerator and the denominator:

  • Both the numerator and the denominator contain the variable aa. We can divide both by aa, resulting in:
  • 146a\frac{14}{6a}

Further simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2:

  • 14÷26÷2a=73a\frac{14 \div 2}{6 \div 2a} = \frac{7}{3a}

Thus, the simplified form of the expression is 73a\frac{7}{3a}.

Therefore, the solution to the problem is 73a\frac{7}{3a}.
