Answer 1

70/51

2/5

3/8

4/3

Answer 2

a) 70/51

b) 2/5

c) 3/8

d) 25/12

Answer 3

\(a\dfrac{19}{17}+\dfrac{13}{51}=\dfrac{57+13}{51}=\dfrac{70}{51}\)

\(b\dfrac{26}{30}-\dfrac{7}{15}=\dfrac{13}{15}-\dfrac{7}{15}=\dfrac{6}{15}\)

\(c\dfrac{1}{4}\times\dfrac{3}{2}=\dfrac{1\times3}{4\times2}=\dfrac{3}{8}\)

\(d\dfrac{5}{3}:\dfrac{4}{5}=\dfrac{5}{3}\times\dfrac{5}{4}=\dfrac{25}{12}\)

Answer 4

a) \(\dfrac{19}{17}+\dfrac{13}{51}=\dfrac{57}{51}+\dfrac{13}{51}=\dfrac{70}{51}\)

b) \(\dfrac{26}{30}-\dfrac{7}{15}=\dfrac{26}{30}-\dfrac{14}{30}=\dfrac{12}{30}=\dfrac{2}{5}\)

c) \(\dfrac{1}{4}\) X \(\dfrac{3}{2}\) \(=\dfrac{1x3}{4x2}=\dfrac{3}{8}\)

d) \(\dfrac{5}{3}:\dfrac{4}{5}=\dfrac{5}{3}x\dfrac{5}{4}=\dfrac{25}{12}\)
