Use the fact that 1 yards equals 3 feet.

About 5.7

Practice makes perfect

We want to express 17 feet in yards. 17 ft = yd We can do this by using the fact that 1 yards equals 3 feet. Let's write this relationship as a unit ratio. 3 ft/1yd To perform the conversion, we need to multiply 17 feet by the unit ratio or its reciprocal. Remember, we want to get the distance in yards, and every unit we do not want has to be divided out.

17 ft = 17 ft * 1 yd/3ft
17 ft = 17 ft/1 * 1 yd/3ft
17 ft = 17 ft* 1 yd/1* 3ft
17 ft = 17 ft* 1 yd/1* 3ft
17 ft= 17 * 1 yd/1* 3
17 ft= 17 yd/3
17 ft= 5.666666... yd
17 ft≈ 5.7 yd

We found that 17 feet is equal to about 5.7 yards. We can now complete the given statement. 17 ft≈ 5.7 yd
