Question

4/7 : X + 1/2 = 3

Answer 1

\(\dfrac{4}{7}:x+\dfrac{1}{2}=3\\ \Rightarrow\dfrac{4}{7}:x=3-\dfrac{1}{2}\\ \Rightarrow\dfrac{4}{7}:x=\dfrac{5}{2}\\ \Rightarrow x=\dfrac{4}{7}:\dfrac{5}{2}\\ \Rightarrow x=\dfrac{8}{35}\)

Answer 2

4/7:x= 3-1/2

4/7:x=5/2

x=4/7:5/2

x=8/35

Answer 3

4/7 : X = 3 -1/2

4/7 : X = 5/2

X = 5/2 : 4/7

X = 8/35
