Question

       Tính

31/25 + ( 15/16 - 6/15 ) +1/16

Answer 1

           \(\frac{31}{25}\) + ( \(\frac{15}{16}\) - \(\frac{6}{15}\) ) + \(\frac{1}{16}\)

           = \(\frac{31}{25}\) + \(\frac{43}{80}\) + \(\frac{1}{16}\)

           = \(\frac{711}{400}\) + \(\frac{1}{16}\) 

           = \(\frac{46}{25}\)

Answer 2

\(\frac{31}{25}+\left(\frac{15}{16}-\frac{6}{15}\right)+\frac{1}{16}=\frac{31}{25}+\frac{15}{16}-\frac{6}{15}+\frac{1}{16}\) 

\(\frac{31}{25}-\frac{6}{15}+1=\frac{31}{25}-\frac{10}{25}+\frac{25}{25}=\frac{46}{25}\)

Answer 3

   31/25 + ( 15/16 - 6/15 ) + 1/16

= 31/25 + 15/16 - 6/15 + 1/16

= ( 31/25 - 6/15 ) + ( 15/16+ 1/16 )

= 21/5 + 1

= 46/25
