Question

Give 3 ratios that are proportional to 4 : 9.

✓

Answer

To find ratios proportional to $4: 9$, we multiply both terms by the same number :
$\begin{array}{l}4 \times 2 : 9 \times 2=8: 18 \\4 \times 3 : 9 \times 3=12: 27 \\4 \times 5 : 9 \times 5=20 : 45\end{array}$
So, three ratios proportional to $4: 9$ are $8 : 18 ; 12 : 27$; and $20: 45$.
