Step-by-step explanation
So we have a ratio of 3 feet to 63 inches and we must write it as a fraction. The first thing to do is convert feet to inches so we have both parts in the same unit. According to the table there are 12 inches in 1 foot so 3 feet is equivalent to:
![3\text{ ft}=3\cdot12\text{ in}=36\text{ in}](https://img.qammunity.org/2023/formulas/mathematics/college/cl8708bhv8be0g1l5finivp23vfwxhstv3.png)
So the ratio is 36 inches to 63 inches. In order to express it as a fraction we must take the left part and divide it by the right part:
![(36)/(63)=(9\cdot4)/(9\cdot7)=(4)/(7)](https://img.qammunity.org/2023/formulas/mathematics/college/a5bgkr9gwb8yp24bsy3fd5xccw61xvp3xd.png)
