Question

\(\frac{1}{10}+\frac{9}{10}+\frac{10}{10}+9+\frac{160}{2}\)

Answer 1

       \(\frac{1}{10}+\frac{9}{10}+\frac{10}{10}+9+\frac{160}{2}\)

\(=\frac{10}{10}+\frac{10}{10}+9+\frac{160}{2}\)

\(=1+1+9+80\)

\(=91\)

Answer 2

Ta có \(\frac{1}{10}+\frac{9}{10}+\frac{10}{10}+9+\frac{160}{2}=\left(\frac{1}{10}+\frac{9}{10}\right)+\left(\frac{10}{10}+9\right)+\frac{160}{2}\)

\(=1+10+80\)

\(=91\)

Vậy giá trị biểu thức là 91 

Answer 3

\(\frac{1}{10}+\frac{9}{10}+\frac{10}{10}+9+\frac{160}{2}\)

\(=\) \(2+9+80\)

\(=\)\(91\)

Answer 4

    \(\frac{1}{10}+\frac{9}{10}+\frac{10}{10}+9+\frac{160}{2}\)

= \(\frac{10}{10}+\frac{10}{10}+9+\frac{160}{2}\)

= \(1+1+9+80\)

= \(91\)
