Multiply the following fractions, simplifying by cross-cancellation where possible: 16/4 14/4 16/18

First, simplify $\frac{16}{4}$ to $\frac{4}{1}$.

$$\frac{4}{1} \times \frac{14}{4} \times \frac{16}{18}$$

Next, simplify $\frac{14}{4}$ by dividing both numerator and denominator by 2, resulting in $\frac{7}{2}$.

$$\frac{4}{1} \times \frac{7}{2} \times \frac{16}{18}$$

Then, simplify $\frac{16}{18}$ by dividing both numerator and denominator by 2, resulting in $\frac{8}{9}$.

$$\frac{4}{1} \times \frac{7}{2} \times \frac{8}{9}$$

Now, we can cross-cancel 4 (numerator of the first fraction) with 2 (denominator of the second fraction). Divide 4 by 2 to get 2, and 2 by 2 to get 1.

$$\frac{2}{1} \times \frac{7}{1} \times \frac{8}{9}$$

There are no more common factors for cross-cancellation.

Multiply the numerators: $2 \times 7 \times 8 = 14 \times 8 = 112$.
Multiply the denominators: $1 \times 1 \times 9 = 9$.

$$\frac{112}{9}$$

The fraction $\frac{112}{9}$ cannot be simplified further.
