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

Answer 1

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

Answer 2

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

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

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

\(=201,5.14\)

\(=2821\)

Answer 3

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

Answer 4

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