201.5:0.5+201;5:0,125

= 201,5:(0.5+0.125)

=201.5:0.625

=332.4

201,5 : 0,5 + 201,5 : 0,125

= 201,5 x 2 + 201,5 x 8

= 201,5 x (2+8)

= 201,5 x 10

= 2015

201,5 : 0,5 + 201,5 :0,125

= 201,5 x 2 + 201,5 x 8

= 201,5 x ( 2 + 8 )

= 201,5 x 10

= 2015 

\(201.5:\left(\frac{1}{8}+\frac{1}{4}-\frac{1}{2}\right)=201,5:-\frac{1}{8}=\frac{2015}{1000}x\frac{-8}{1}=\frac{16120}{1000}=156.12\)

\(201,5:\frac{1}{8}+201,5:\frac{1}{4}+201,5:\frac{1}{2}\)

\(=201,5.8+201,5.4+201,5.2\)

\(=201,5.\left(8+4+2\right)\)

\(=201,5.14\)

\(=2821\)

k mk nha ! Mà hiểu chấm là nhân nha !

=\(201,5:\left[\frac{1}{8}+\frac{1}{4}+\frac{1}{2}\right]=\frac{1612}{7}\)

= 2015 

kb vs mik nhe 

k nua nha ^^

201 5 : 1/8 + 201,5 : 1/4 - 201,5 : 1/2
