Exercise 12 Page 323

Use the fact that 1 foot equals about 0.30 meter.

About 24 m

Practice makes perfect

We want to express 80 feet in meter. 80 ft≈ m We can do this by using the fact that 1 foot equals about 0.30 meter. Let's write this relationship as a unit ratio. 0.30 m/1ft To perform the conversion, we need to multiply 80 feet by the unit ratio or its reciprocal. Remember, we want to get the height in meters, and every unit we do not want has to be divided out.

80 ft≈ 80 ft * 0.30 m/1ft
80 ft≈ 80 ft/1 * 0.30 m/1ft
80 ft≈ 80 ft* 0.30 m/1* 1ft
80 ft≈ 80 ft* 0.30 m/1* 1ft
80 ft≈ 80 * 0.30 m/1* 1
80 ft≈ 24 m/1
80 ft≈ 24 m

We found that the tree is about 24 meters high.
