Question

simplify 4 3/5 - 2 7/9 - 1 2/15 - 2/45​

Answer 1

Answer:

$\huge{\fcolorbox{black}{pink}{\fcolorbox{pink}{black}{\bf{\color{pink}{⚘ÃñSwÉr⚘}}}}}$

$\large{= > 4 \frac{3}{5} - 2 \frac{7}{9} - 1 \frac{2}{15} - \frac{2}{45}}$

$\large{= > ( \frac{23}{5} - \frac{25}{9} )- (\frac{17}{15} - \frac{2}{45} ) \: \: \sf{(by \: associativity)}}$

$\large{= > (\frac{207 - 125}{45} ) - ( \frac{51 - 2}{45} )}$

$\large{= > \frac{82}{45} - \frac{49}{45}}$

$\large{= > \frac{82 - 49}{45}}$

$\large{ = > \frac{33}{45} }$
