Simplify the fractions by cross-cancellation: 18/8 15/3 16/4

Here are the solutions for the fraction multiplication problems:

: $\frac{18}{8} \times \frac{15}{3} \times \frac{16}{4}$

Step 1: Simplify the fractions by cross-cancellation.

$$\frac{18}{8} \times \frac{15}{3} \times \frac{16}{4}$$

Cancel 15 and 3: $15 \div 3 = 5$, $3 \div 3 = 1$.
Cancel 16 and 4: $16 \div 4 = 4$, $4 \div 4 = 1$.
