Question

[0,(63) + 0,(36)] : \(\left[0,\left(3\right).3+0,\left(231\right):\frac{77}{333}\right]\)

 

Answer 1

\(\left[\frac{7}{11}+\frac{4}{11}\right]:\left[\frac{1}{3}.3+\frac{77}{333}:\frac{77}{333}\right]\)

= 1 : [ 1 + 1 ]

= 1 : 2

= \(\frac{1}{2}\)

Answer 2

\(\left[0,\left(63\right)+0,\left(36\right)\right]:\left[0,\left(3\right)+0,\left(231\right):\frac{77}{333}\right]\)

\(=\left[\frac{63}{99}+\frac{36}{99}\right]:\left[\frac{3}{9}.3+\frac{231}{999}\cdot\frac{333}{77}\right]\)

\(=1:\left[1+1\right]=\frac{1}{2}\)

Answer 3

[0,(63)+0,(36)]:[0,(3).3+0,(231:77/333]

=[7/11+4/11]:[1/3.3+7/3:77/333

= 1: [ 1+111/11]

=1:122/11

=11/122

Answer 4

mình viết nhầm 

1:(1+77/333:77/333)

=1:(1+1)

=1:2

=1/2
