          Bài 1 TÍNH          

\(\frac{5}{16}:0,125-\left(2\frac{1}{4}-0,6\right).\frac{10}{11}\)

\(49\frac{8}{23}-\left(5\frac{7}{32}+14\frac{8}{23}\right)\)

Answer 1

Bài 1:

5/16:0,125-(2 1/4-0,6).10/11

=5/16:5/4-(9/4-3/5).10/11

=1/4-33/20.10/11

=1/4-3/2

=-5/4

Answer 2

\(\frac{5}{16}:0,125-\left(2\frac{1}{4}-0,6\right).\frac{10}{11}\)

\(=\frac{5}{16}.8-\frac{33}{20}.\frac{10}{11}\)

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

\(49\frac{8}{23}-19\frac{417}{736}\)

\(=\frac{953}{12}\)

Study well 

Answer 3

\(\frac{5}{16}:0,125-\left(2\frac{1}{4}-0,6\right).\frac{10}{11}\)ư

= \(\frac{5}{16}:\frac{1}{8}-\left(\frac{9}{4}-\frac{3}{5}\right).\frac{10}{11}\)

= \(\frac{5}{16}.8-\left(\frac{9}{4}-\frac{3}{5}\right).\frac{10}{11}\)

= \(\frac{5}{2}-\left(\frac{45}{20}-\frac{12}{20}\right).\frac{10}{11}\)

= \(\frac{5}{2}-\frac{33}{20}.\frac{10}{11}\)

= \(\frac{5}{2}-\frac{3}{2}\)

= \(1\)

b) \(49\frac{8}{23}-\left(5\frac{5}{32}+14\frac{8}{23}\right)\)

= \(49\frac{8}{23}-5\frac{7}{32}-14\frac{8}{23}\)

= \(\left(49\frac{8}{23}-14\frac{8}{23}\right)-5\frac{7}{32}\)

= \(35-\frac{167}{32}\)

= \(\frac{1120}{32}-\frac{167}{32}\)

= \(\frac{953}{32}\)

Chúc bạn học tốt !!!
