lấy máy tính ra bấm là nó ra liền à

\(\frac{-35}{280}=\frac{\left(-35\right):35}{280:35}=\frac{-1}{8}\)     

\(\frac{24}{72}=\frac{24:24}{72:24}=\frac{1}{3}\)

\(\frac{15}{-105}=\frac{-15}{105}=\frac{\left(-15\right):15}{105:15}=\frac{-1}{7}\)

\(\frac{36}{240}=\frac{36:12}{240:12}=\frac{3}{20}\)

\(\frac{125}{1000}=\frac{125:125}{1000:125}=\frac{1}{8}\)

\(\frac{198}{126}=\frac{198:18}{126:18}=\frac{11}{7}\)
