1. The first problem is to calculate the division of numbers as fractions. 2. We use the formula for division of numbers: $$\frac{a}{b}$$ means $a$ divided by $b$. 3. Calculate each division: - $$\frac{10}{2} = 5$$ - $$\frac{10}{3} \approx 3.33$$ (rounded to two decimals) - $$\frac{10}{4} = 2.5$$ - $$\frac{10}{5} = 2$$ - $$\frac{12}{5} = 2.4$$ - $$\frac{13}{6} \approx 2.17$$ (rounded to two decimals) - $$\frac{13}{7} \approx 1.86$$ (rounded to two decimals) - $$\frac{31}{8} = 3.875$$ 4. For the juice bottles problem: - Eva has 7 bottles. - Each bottle contains half a litre, so total juice is $$7 \times \frac{1}{2} = \frac{7}{2} = 3.5$$ litres. This means Eva has 3.5 litres of juice in total.
