\(201.5:\left(\frac{1}{8}+\frac{1}{4}-\frac{1}{2}\right)=201,5:-\frac{1}{8}=\frac{2015}{1000}x\frac{-8}{1}=\frac{16120}{1000}=156.12\)
\(201,5:\frac{1}{8}+201,5:\frac{1}{4}+201,5:\frac{1}{2}\)
\(=201,5.8+201,5.4+201,5.2\)
\(=201,5.\left(8+4+2\right)\)
\(=201,5.14\)
\(=2821\)
k mk nha ! Mà hiểu chấm là nhân nha !
=\(201,5:\left[\frac{1}{8}+\frac{1}{4}+\frac{1}{2}\right]=\frac{1612}{7}\)
nhầm ,phải = \(201,5:\left[\frac{1}{8}+\frac{1}{4}-\frac{1}{2}\right]=-1612\)
