\(\frac{5}{16}+\frac{5}{7}+0,4+\frac{1}{6}-\frac{4}{35}\)

= \(\frac{5}{16}+\frac{25}{35}+\frac{2}{5}+\frac{1}{6}-\frac{4}{35}\)

= \(\frac{5}{16}+\frac{2}{5}+\frac{1}{6}+\frac{25}{35}-\frac{4}{35}\)

= \(\frac{5}{16}+\frac{2}{5}+\frac{1}{6}+\frac{2}{3}\)

= \(\frac{5}{16}+\frac{2}{5}+\frac{5}{6}\)

= \(\frac{5}{16}+\frac{37}{30}\)

= \(\frac{371}{240}\)

a,45,75+25,5x3,5-35

=45,75+(25,5x3,5)-35

=45,75+89,25-35

=135-35

=100

b,166,32:46,2+16x0,4

=(166,32:46,2)+(16x0,4)

=3,6+6.4

=10

kết quả bằng 9,65

9,65x0,4x2,5

=9,65x(0,4x2,5)

=9,65x1

=9,65

7,8 + 5,6 + 4,2 + 0,4 =(7,8 + 4,2) + (5,6 + 0,4)

= 12 + 6 = 18

7,8 + 5,6 + 4,2 + 0,4

= (7,8 + 4,2 ) + ( 5,6 + 0,4 )

=       12         +        6

=                   18

nha bạn

35,5 : 0,125 + 35,5 x 2

= 35,5 x 8 + 35,5 x 2

= 35,5 x (8+2)

= 35,5 x 10 

= 355

25,5 : 0,5 + 25,5 x 8

= 25,5 x 2 + 25,5 x 8

= 25,5 x (2+8)

= 25,5 x 10

= 255

nhớ ghi đầy đủ lời giải nhé

25,5 : 0,5 + 25,5 \(\times\)8 

= 25,5 \(\times\) 2 + 25,5 \(\times\)8

= 25,5 \(\times\) ( 2 + 8)

= 25,5 \(\times\)10 

= 255

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

\(101\times2,022-2,022\\ =\left(101-1\right)\times2,022\\ =100\times2,022\\ =202,2\)

\(101\times2,022-2,022\)

\(=2,022\)\(\times\left(101-1\right)\)

\(=2,022\times100\)

\(=202,2\)

\(101\times2,022-2,022\)
\(=101\times2,022-2,022\times1\)
\(=\left(101-1\right)\times2,022\)
\(=100\times2,022\)
\(=202,2\)
