Question: $$0 . 1 5 \div 0 . 3$$

Solution

To solve the expression \(0.15 \div 6.3\), follow these steps: Convert the division of decimals into fraction form: \[ \frac{0.15}{6.3} \] To simplify, eliminate the decimals by multiplying the numerator and the denominator by 10: \[ \frac{0.15 \times 10}{6.3 \times 10} = \frac{1.5}{63} \] Simplify the fraction \(\frac{1.5}{63}\): \[ \frac{1.5}{63} = \frac{15}{630} = \frac{1}{42} \] Therefore, the result of \(0.15 \div 6.3\) is \(\frac{1}{42}\). The answer is \(\frac{1}{42}\).
