co ai biet thi giai giup minh nhe

Answer 1

\(\frac{2}{5}\)x \(\frac{3}{2}\)- \(\frac{3}{8}\) : \(\frac{5}{6}\)+ \(\frac{17}{20}\)

= \(\frac{3}{5}\)- \(\frac{3}{8}\) : \(\frac{5}{6}\)+ \(\frac{17}{20}\)

= \(\frac{9}{40}\): \(\frac{5}{6}\)+ \(\frac{17}{20}\)

= \(\frac{27}{100}\)+ \(\frac{17}{20}\)

= \(\frac{28}{25}\)

Answer 2

\(\frac{2}{5}.\frac{3}{2}-\frac{3}{\frac{8}{\frac{5}{6}}}+\frac{17}{20}\)

\(\frac{3}{5}-\frac{5}{16}+\frac{17}{20}\)

\(\frac{23}{80}+\frac{17}{20}\)

\(\frac{91}{80}\)

Answer 3

2/5 * 3/2 - 3/8 / 5/6 +17/20

= 3/5 - 9/20 + 17/20

=3/20 + 17/20

= 1

Answer 4

2/5-3/2-3/8/5/6+17/20

6/10-24/40+17/20

24/40-24/40+34/40

34/40=17/20

Answer 5

23/40
