\(\frac{9}{5}:\frac{17}{15}+\frac{8}{5}:\frac{17}{15}\)

\(=\frac{17}{15}:\left(\frac{9}{5}+\frac{8}{5}\right)\)

\(=\frac{17}{15}:3\)

\(=\frac{17}{45}\)

\(\frac{9}{5}:\frac{17}{15}+\frac{8}{5}:\frac{17}{5}=\frac{9}{5}.\frac{15}{17}+\frac{8}{5}.\frac{15}{17}=\frac{15}{17}\left(\frac{9}{5}+\frac{8}{5}\right)=\frac{15}{17}.\frac{17}{5}=3\)

   9/5 : 17/15 + 8/5 : 17/15

= ( 9/5 + 8/5 ) x 15/17

= 17/5 x 15/17

= 3

16x48+8x48+32x14

=48x(16+8)+32x14

=48x24+32x14

=1152+448

=1600

16 x 48 + 8 x 48 + 32 x 14

= 48 x (16 + 14) x (32 + 8)

=48 x 20 x 40

=38400

( 48 + 32 + 56 ) : 8

= 48 : 8 + 32 : 8 + 56 : 8

= 6 + 4 + 7 = 10 + 7 = 17

kết quả là 17

=136:8

=17

( 48 + 32 + 56 ) : 8

= (48 : 8) + (32 : 8) + (56 : 8)

= 6 + 4 + 7

= 10 + 7

= 17

200,6 : 12 ,5 : 0,8

= 200,6 : ( 12,5 x 0,8 ) 

= 200,6 : 10

= 20, 06 

k mình nhé 

200,6:12,5:0,8

=200,6:10

=20,06

tk mình nha

thank you bạn

thank le anh tu

\(\dfrac{1}{3}+\dfrac{6}{5}-\dfrac{1}{5}+\dfrac{2}{3}=2\)

=346x75+346x1+20x346+346x4
=346x(75+1+20+4)
=346x100
=34600

\(346\times75+346+20\times346+346\times4\)

\(=346\times\left(75+20+4+1\right)\)

\(=346\times100\)

\(=34600\)

= 346x(75+1+20+4)
= 346x100
= 34600

Tính bằng cách thuận tiện nhất: 2,5x12,5x8x0,4=100

k mik nha
