Exercise 35 Page 24

Use the conversion factor that 1 feet is equal to 12 inches.

2 feet=24 inches

Practice makes perfect
We are asked to express 2 feet in inches. 2 feet= inches To do so, we will use the fact that 1 feet is equal to 12 inches. Let's write this relationship as a unit ratio. 12 in./1feet To perform the conversion, we need to multiply 2 feet by the unit ratio or its reciprocal. Remember, we want to arrange this ratio such that every unit we do not want gets canceled out and only the unit that we want will remain.
2 ft= 2 ft * 12 in./1ft
2 ft = 2 ft/1 * 12 in./1ft
2 ft = 2 ft* 12 in./1* 1ft
2 ft = 2 ft* 12 in./1* 1ft
2 ft = 2 * 12 in./1* 1
2 ft = 24 in./1
2 ft = 24/1 in.
2 ft = 24 in.
We got that 2 feet is equal to 24 inches. 2 feet=24 inches
