1.2

Recall the following rule: $\frac{a}{b} \div \frac{c}{d}=\frac{a}{b} \times \frac{d}{c}$. We convert the decimal into a fraction for the ease of simplification: $1.56\div1.3$ =$\frac{156}{100}\div\frac{13}{10}$ =$\frac{156}{100}\times\frac{10}{13}$ =$\frac{156}{10}\times\frac{1}{13}$ =$\frac{12}{10}\times\frac{1}{1}$ =$1.2$
