Penjelasan dengan langkah-langkah:

5/8 × 8/9 + 3/2 ÷ 5/2 - 8/5

= (5/8 × 8/9) + (3/2 × 2/5) - 8/5

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

= 25/45 + 27/45 - 72/45

= (-20/45)

= (-4/9)

$\frac{5}{8} \times \frac{8}{9} + \frac{3}{2} \div \frac{5}{2} - \frac{8}{5}$

$= \frac{5 \times 8}{8 \times 9} + \frac{ \frac{ \frac{3}{2} }{5} }{2} - \frac{8}{5}$

$= \frac{40}{81} + \frac{ \frac{ \frac{3}{2} }{5} }{2} - \frac{8}{5}$

$= \frac{5}{9} + \frac{ \frac{ \frac{3}{2}}{5} }{2} - \frac{8}{5}$

$= \frac{5}{9}+\frac{3}{2}\times \left(\frac{2}{5}\right)-\frac{8}{5}$

$= \frac{5}{9}+\frac{3\times 2}{2\times 5}-\frac{8}{5}$

$= \frac{5}{9} + \frac{6}{10} - \frac{8}{5}$

$= \frac{5}{9}+\frac{3}{5}-\frac{8}{5}$

$= \frac{25}{45}+\frac{27}{45}-\frac{8}{5}$

$= \frac{25+27}{45}-\frac{8}{5}$

$= \frac{52}{45}-\frac{8}{5}$

$= \frac{52}{45}-\frac{72}{45}$

$= \frac{52-72}{45}$

$= \frac{-20}{45}$

$= - \frac{4}{9}$
