Question

\(\dfrac{1}{5}\)x\(\dfrac{7}{6}\)+\(\dfrac{1}{5}\)x\(\dfrac{5}{16}\)+\(\dfrac{1}{5}\)x\(\dfrac{3}{16}\)

Answer 1

quy đồng ra nhé

Answer 2

( 7/6 + 5/16 + 3/16) x 1/5

= ( 7/6 + 1/2) x 1/5

= ( 7/6 + 3/6) x 1/5

= 10/6 x 1/5

= 5/3 x 1/5 

=1/3

Answer 3

1/5 x 7/6 + 1/5 x 5/16 + 1/5 x 3/16
=1/5 x (7/6 + 5/16 + 3/16)
=1/5 x (7/6 + 1/2)
=1/5 x (7/6 + 3/6)
=1/5 x 10/6
=2/6=1/3

Answer 4

`=1/5xx(7/6+5/16+3/16)`

`=1/5xx5/3=+/3`
