The ratio of 6 inch to 4 feet will be

To find the ratio, both measurements must be converted to the same unit. We know that:
$1\text{foot}=12\text{inches}$

Therefore, converting $4\text{feet}$ into inches gives:
$4\text{feet}=4\times 12=48\text{inches}$

Now, we can compute the required ratio:

$$\text{Ratio}=\frac{6\text{inches}}{48\text{inches}}=\frac{1}{8}=1:8$$
