Answer 1

$\bold{\dfrac{5}{12}-\dfrac{3}{8}+\dfrac{1}{4} \ = \ \dfrac{7}{24}}\\ \\ \\1) \ \dfrac{5}{12}-\dfrac{3}{8} \ = \ \dfrac{5\cdot2}{12\cdot2}-\dfrac{3\cdot3}{8\cdot3} \ = \ \dfrac{10}{24}-\dfrac{9}{24} \ = \ \dfrac{1}{24} \\ \\ \\2) \ \dfrac{1}{24}+\dfrac{1}{4} \ = \ \dfrac{1}{24}+\dfrac{1\cdot6}{4\cdot6} \ = \ \dfrac{1}{24}+\dfrac{6}{24} \ = \ \dfrac{7}{24} \\ \\ \\ \\\bold{OTBET: \dfrac{7}{24}}$
