Question

a) 5/2 x 1/3 + 1/4 

b) 5/2 - 1/3 : 1/4

Answer 1

\(a,\dfrac{5}{2}\times\dfrac{1}{3}+\dfrac{1}{4}=\dfrac{5}{6}+\dfrac{1}{4}=\dfrac{13}{12}\\ b,\dfrac{5}{2}-\dfrac{1}{3}:\dfrac{1}{4}=\dfrac{5}{2}-\dfrac{4}{3}=\dfrac{7}{6}\)

Answer 2

a) \(\dfrac{5}{2}\times\dfrac{1}{3}+\dfrac{1}{4}=\dfrac{5}{6}+\dfrac{1}{4}=\dfrac{10}{12}+\dfrac{3}{12}=\dfrac{13}{12}\)

b) \(\dfrac{5}{2}-\dfrac{1}{3}:\dfrac{1}{4}=\dfrac{5}{2}-\dfrac{1}{3}\times4=\dfrac{5}{2}-\dfrac{4}{3}=\dfrac{15}{6}-\dfrac{8}{6}=\dfrac{7}{6}\)

Answer 3

a) = 5/6 + 1/4 = 13/12

b) = 5/2 - 4/3 = 7/6
