Question

Answer 1

\(a,\dfrac{7}{8}-\dfrac{5}{8}=\dfrac{2}{8}=\dfrac{1}{4}\\ b,\dfrac{13}{9}-\dfrac{4}{9}=\dfrac{9}{9}=1\\ c,\dfrac{21}{14}-\dfrac{9}{14}=\dfrac{12}{14}=\dfrac{6}{7}\\ d,\dfrac{43}{54}-\dfrac{7}{54}=\dfrac{36}{54}=\dfrac{2}{3}\)

Answer 2

a) \(\dfrac{7}{8}-\dfrac{5}{8}=\dfrac{2}{8}=\dfrac{1}{4}\)

b) \(\dfrac{13}{9}-\dfrac{4}{9}=\dfrac{9}{9}=1\)

c) \(\dfrac{21}{14}-\dfrac{9}{14}=\dfrac{12}{14}=\dfrac{6}{7}\)

d) \(\dfrac{43}{54}-\dfrac{7}{54}=\dfrac{36}{54}=\dfrac{2}{3}\)
