Answer 1

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

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

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

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

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

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

Answer 3

   1/2 : 2/3 – 1/5

=1/2 x 3/2 – 1/5

=2/5 – 1/5

=1/5

   1/4 x 5/3 + 3/2

=5/12 + 3/2

=5/12 + 18/12

=23/12

Thông cảm nhé, máy ko viết đc PS

Answer 4

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

\(=\frac{5}{12}\)\(+\frac{3}{2}\)

\(=\frac{5}{12}\)\(+\frac{18}{12}\)

\(=\frac{23}{12}\)

Answer 5

TL:

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

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

Answer 8

H heeeehuy

Answer 9

1/2 : 2/3 - 1/5

= 1/2 × 3/2 - 1/5

= 3/4 - 1/5

= 11/20

1/4 × 5/3 + 3/2 

= 5/12 + 3/2

= 23/12
