Begin by converting feet to inches using the fact that 1 foot is equal to 12 inches.
156:7
Practice makes perfect
We have been given a sculpture that is a model of a cornet.
Given that the length of the sculpture is 26 feet and the length of a standard cornet is 14 inches, we will find the scale factor of the sculpture to a standard cornet. Let's first convert feet to inches using the fact that 1 foot is equal to 12 inches.
26 ft * 12 in./ft=312 in.
Now, we can find the scale factor by finding the ratio of the length of the sculpture to the length of the cornet.
312/14=156/7 ⇔ 156:7
The scale factor is 156:7.
