Answer 1

$15frac{6}{37}-(7-4frac{8}{37})-(frac{39}{37}+1frac{35}{37})=\\=underbrace {15+frac{6}{37}}-(underbrace {7-(4}+frac{8}{37}))-(underbrace {1+frac{2}{37}}+1+frac{35}{37})=\\=15+frac{6}{37}-(3-frac{8}{37})-(2+underbrace {frac{37}{37}}_{1})=\\=(15-3-2-1 )+(frac{6}{37}+frac{8}{37})=9+frac{14}{37}=9frac{14}{37}$
