Помогите  пожалуйста с примером

Answer 1

$(1frac{11}{24}+frac{13}{36})cdot1,44-frac{8}{15}cdot0,5625=2,32$

 

1) $1frac{11}{24}+frac{13}{36}=<var>1frac{33}{72}+frac{26}{72}=1frac{59}{72}</var>$

 

2) $<var>1frac{59}{72}cdot1,44=frac{131}{72}cdot frac{144}{100}=2,62</var>$

 

3) $frac{8}{15}cdot0,5625=frac{8}{15}cdot frac{5625}{10000}=0,3$

 

4) $2,62-0,3=2,32$
