Question

3/7 +-10/21 -4/3

Answer 1

\(\dfrac{3}{7}+\dfrac{-10}{21}-\dfrac{4}{3}\)

\(=\dfrac{3}{7}-\dfrac{10}{21}-\dfrac{4}{3}\)

\(=\dfrac{3.3}{7.3}-\dfrac{10}{21}-\dfrac{4.7}{3.7}\)

\(=\dfrac{9}{21}-\dfrac{10}{21}-\dfrac{28}{21}\)

\(=\dfrac{9-10-28}{21}\)

\(=-\dfrac{29}{21}\)

Answer 2

3/7 +-10/21 -4/3

= -1/21 - 4/3

= -29/21

Answer 3

`3/7+(-10/21)-4/3`

`=(9-10-28)/21`

`=-29/21`

Answer 4

\(\dfrac{3}{7}+\dfrac{-10}{21}-\dfrac{4}{3}\\ =\dfrac{3}{7}-\dfrac{10}{21}-\dfrac{4}{3}\\ =-\dfrac{1}{21}-\dfrac{4}{3}\\ =-\dfrac{29}{21}\)
