Question

Answer 1

a: \(\frac{4}{-25}+\frac{-9}{-35}\)

\(=\frac{-4}{25}+\frac{9}{35}\)

\(=-\frac{28}{175}+\frac{45}{175}=\frac{17}{175}\)

b: \(\frac{-15}{-22}+\frac{-6}{25}=\frac{15}{22}-\frac{6}{25}\)

\(=\frac{375}{550}-\frac{132}{550}=\frac{243}{550}\)

c: \(\frac{4}{-5}+2=-\frac45+\frac{10}{5}=\frac65\)

d: \(3+\frac{-6}{5}=\frac{15}{5}-\frac65=\frac95\)
