**6. Calculate \(3.16 \div 10\)** Dividing by 10 shifts the decimal point one place to the left: \[ 3.16 \div 10 = 0.316 \] --- **7. Calculate \(40.5 \div 25\)** We write the expression as a fraction: \[ \frac{40.5}{25} \] One way to simplify is to eliminate the decimal in the numerator by multiplying both numerator and denominator by 2: \[ \frac{40.5 \times 2}{25 \times 2} = \frac{81}{50} \] Now, dividing: \[ \frac{81}{50} = 1.62 \] --- **8. Calculate \(34.75 \div 1000\)** Dividing by 1000 shifts the decimal point three places to the left: \[ 34.75 \div 1000 = 0.03475 \] --- **9. Calculate \(245.25 \div 50\)** We express the division as: \[ \frac{245.25}{50} \] Notice that dividing by 50 is the same as dividing by 100 and then multiplying by 2: \[ 245.25 \div 100 = 2.4525 \] Then, \[ 2.4525 \times 2 = 4.905 \] Thus, \[ 245.25 \div 50 = 4.905 \]
