48% + 0,6 + \(\frac{13}{25}\)

= \(\frac{12}{25}+\frac{15}{25}+\frac{13}{25}\)

= \(\frac{8}{5}\)

kết quả là 8/5

\(48\%+0.6+\frac{13}{25}=\frac{12}{25}+\frac{13}{25}+0.6=1+0.6=1.6\)

2016 x 101 – 2016

= 2016 x 101 – 2016 x 1

= 2016 x ( 101 -1)

= 2016 x 100

= 201600

2017 x ( 101 - 1 ) = 2017 x 100

                            = 201700

Đáp án: 48 x 84 + 16 x 48

= 48 x (84 + 16)

= 48 x 100

             = 4800

   48 x 84 + 16 x 48

= 48 x (84 + 16)

= 48 x 100

= 4800

48 x 84 + 16 x 48

= 48 x (84 + 16)

= 48 x 100

= 4800

101.9,42-9,42+25.2,32

=9,42.(101-1)+58

=9,42.100+58

=942+58=1000

   101 x 9,42 - 9,42 + 25 x 2,32

=  101 x 9,42 - 9,42 x 1 + 25 x 2,32

= 9,42 x ( 101 - 1) + 58

= 9,42 x 100 + 58

= 942 + 58

= 1000
