Example Question - halving a

Proportional Relationship Calculation

To solve the question, we need to assume there is a proportional relationship between \( b \) and \( a \). Given that \( b = 8 \) when \( a = 16 \), we can say that \( b \) is half the value of \( a \) in this context. Using this proportionality, if \( a = 18 \), we can calculate the value of \( b \) by halving \( a \): \[ b = \frac{a}{2} \] \[ b = \frac{18}{2} \] \[ b = 9 \] Therefore, if \( a = 18 \), then \( b = 9 \).
