5•356•843:4

To solve the expression \( 5 \cdot 356 \cdot \frac{843}{4} \), we can follow these steps:

1. Calculate \( 843 \div 4 \): \[ 843 \div 4 = 210.75 \]

2. Now, multiply \( 5 \) and \( 356 \): \[ 5 \cdot 356 = 1780 \]

3. Finally, multiply \( 1780 \) by \( 210.75 \): \[ 1780 \cdot 210.75 = 374,385 \]

Thus, \( 5 \cdot 356 \cdot \frac{843}{4} = 374385 \).
