As your ratio states, it's 1 to 18, meaning that the actual motorcycle is 18 times bigger than the model of it.
The question asks us to to find the actual length of the motorcycle, but we only have the model length.
We can solve this problem by transforming model length to the actual length by using ratio.
5.25 times 18 equals to 94.5 inches.
There are 12 inches in one foot.
94.5 divided by 12 equals to 7.875.
Let's not care about the ".875" part, and simply multiply 12 by 7.
12 times 7 equals to 84.
94.5 minus 84 (7 feet) equals to 10.5
7 feet, and 10.5 inches.
