Answer 1

$\it a)\ \dfrac{5}{3}+\dfrac{\ 44^{(2)}}{6}-7=\dfrac{5}{3}+\dfrac{22}{3}-7=\dfrac{27}{3}-7=9-7=2\\ \\ \\ b)\ \dfrac{8}{15}-\dfrac{^{3)}2}{\ 5}+1=\dfrac{8}{15}-\dfrac{6}{15}+1=\dfrac{2}{15}+\dfrac{15}{15}=\dfrac{17}{15}\\ \\ \\ c)\ \dfrac{^{12)}3}{\ 5}-\dfrac{^{5)}7}{12}+\dfrac{^{4)}4}{\ 15}=\dfrac{36-35+16}{60} =\dfrac{17}{60}\\ \\ \\ d)\ \ ^{54)}1-\dfrac{^{2)}4}{27}+\dfrac{^{3)}5}{18}=\dfrac{54-8+15}{54}=\dfrac{61}{54}$

$\it e)\ \dfrac{25}{8}-\dfrac{27^{(3}}{24}-\dfrac{37}{37}=\dfrac{25}{8}-\dfrac{9}{8}-1=\dfrac{16}{8}-1=2-1=1\\ \\ \\ f)\ \dfrac{\ 18^{(3}}{18}-\dfrac{\ 15^{(5}}{30}+\dfrac{9}{6}=\dfrac{6}{6}-\dfrac{3}{6}+\dfrac{9}{6}=\dfrac{12}{6}=2$
