Question

-3/5+8/17+(-5/8)-3/5+9/17

Answer 1

Answer 2

-33/40

Answer 3

\(=-\dfrac{3}{5}+\dfrac{8}{17}-\dfrac{5}{8}-\dfrac{3}{5}+\dfrac{9}{17}\)

\(=1-\dfrac{6}{5}-\dfrac{5}{8}\)

\(=-\dfrac{1}{5}-\dfrac{5}{8}\)

\(=-\dfrac{33}{40}\)

Answer 4

= (-3/5 - 3/5) + (8/17 + 9/17) + (-5/8)

= -6/5 + 17/17 + (-5/8)

= -6/5 + 1 + (-5/8)

= -6/5 + 5/5 + (-5/8)

= -1/5 + (-5/8)

= -8/40 + (-25/40)

= -33/40
