Question

4/15 + 40/17 - 4/30 - 6/17
Tính nhanh hộ mk ạ

 

Answer 1

=(4/15-4/30)+(40/17-6/7)

=2-4/30

=2-2/15=13/15

Answer 2

4/15 + 40/17 - 4/30 - 6/17

= (4/15 - 4/30) + (40/17 - 6/17)

= 2/15 + 2

= 32/15

Answer 3

\(\dfrac{4}{15}+\dfrac{40}{17}-\dfrac{4}{30}-\dfrac{6}{17}=\dfrac{40}{17}-\dfrac{6}{17}+\dfrac{4}{15}-\dfrac{4}{30}=\dfrac{34}{17}+\dfrac{4}{30}=\dfrac{34.30+4.17}{510}=\dfrac{1088}{510}=\dfrac{32}{15}\)

Answer 4

4/15 + 40/17 - 4/30 - 6/17

= (4/15 - 4/30) + (40/17 - 6/17)

= 4/30 + 2

= 32/15

Answer 5

=(\(\dfrac{4}{15}\)-\(\dfrac{4}{30}\))+(\(\dfrac{40}{17}\)-\(\dfrac{6}{17}\))

=\(\dfrac{2}{15}\)+2

=\(\dfrac{32}{15}\)

Answer 6

4/15 + 40/17 - 4/30 - 6/17

= (4/15 - 4/30) + (40/17 - 6/17)

= 2/15 + 2

= 32/15
