Answer 1

[Kirito Asuna]

TL :

\(\frac{1}{2}\): \(\frac{2}{3}\)- \(\frac{1}{5}\)= \(\frac{3}{4}\)- \(\frac{1}{5}\)= \(\frac{11}{20}\)

\(\frac{1}{4}\)x \(\frac{5}{3}\)+ \(\frac{3}{2}\)= \(\frac{5}{12}\)+ \(\frac{3}{2}\)= \(\frac{23}{12}\)

Answer 2

[ღTruzgღ★ - FϏ]

\(\frac{1}{2}\)\(:\frac{2}{3}\)\(-\frac{1}{5}\)

\(=\frac{1}{2}\)\(x\frac{3}{2}\)\(-\frac{1}{5}\)

\(=\frac{3}{4}\)\(-\frac{1}{5}\)

\(=\frac{15}{20}\)\(-\frac{4}{20}\)

\(=\frac{11}{20}\)
