The relationship between n and 4 is n>4
We have,
7[tex] \frac{n}{4} [/tex] > 7
The number 7 which is in multiplication on left hand side of the expression, will come in denominator on right hand side of the expression.
⇒ [tex] \frac{n}{4} [/tex] > [tex] \frac{7}{7} [/tex]
⇒ [tex] \frac{n}{4} [/tex] > 1
Again 4 in denominator from left hand side will come in numerator on right hand side
⇒ n > 4
