Question

1 3/10 (một ba phần mười)- 9/16 - 7/10

Answer 1

\(1\dfrac{3}{10}-\dfrac{9}{16}-\dfrac{7}{10}\\ =\dfrac{13}{10}-\dfrac{9}{16}-\dfrac{7}{10}\\ =\dfrac{6}{10}-\dfrac{9}{16}\\ =\dfrac{3}{5}-\dfrac{9}{16}\\ =\dfrac{48}{80}-\dfrac{45}{80}\\ =\dfrac{3}{80}\)

Answer 2

`1 3/10-9/16-7/10`

`=( (1xx10)+3)/10-9/16-7/10`

`=(10+3)/10-9/16-7/10`

`=13/10-9/16-7/10`

`=(13/10-7/10)-9/16`

`=6/10-9/16`

`=3/5-9/16`

`=(3xx16)/(5xx16)-(9xx5)/(5xx16)`

`=48/80-45/80`

`=3/80`

Answer 3

= 13/10 - 9/16 - 7/10

= 59/80 - 7/10

= 3/80

Answer 4

= 13/10 - 9/16 - 7/10

= 59/80 - 7/10

= 3/80.

Answer 5

`1 3/10 - 9/16 - 7/10`

`= 13/10 - 9/16 - 7/10`

`= 59/80 - 7/10`

`= 3/80`
