1. 5yd=15ft

2.3yd=108in
3.6mi=10560yd
4.4mi=21120ft
5.72in=6ft
6.8ft=2yd and 2ft or 2.6

All are correct!

7.48in=1yd 1 foot or 1.3

9.9680yd=880mi 880yd or 5.5
9.15840ft=3mi

To solve the equations given, you can use the following conversion factors:

1 yard (yd) = 3 feet (ft)
1 mile (mi) = 1760 yards (yd)
1 yard (yd) = 36 inches (in)

Now let's solve each equation step by step:

1. To convert 5 yards to feet:
Since 1 yard is equal to 3 feet, we can multiply 5 by 3 to get:
5 yards * 3 feet/yard = 15 feet.

2. To convert 3 yards to inches:
Since 1 yard is equal to 36 inches, we can multiply 3 by 36 to get:
3 yards * 36 inches/yard = 108 inches.

3. To convert 6 miles to yards:
Since 1 mile is equal to 1760 yards, we can multiply 6 by 1760 to get:
6 miles * 1760 yards/mile = 10560 yards.

4. To convert 4 miles to feet:
Since 1 mile is equal to 5280 feet, we can multiply 4 by 5280 to get:
4 miles * 5280 feet/mile = 21120 feet.

5. To convert 72 inches to feet:
Since 1 foot is equal to 12 inches, we can divide 72 by 12 to get:
72 inches / 12 inches/foot = 6 feet.

6. To convert 8 feet to yards and feet:
Since 1 yard is equal to 3 feet, we can divide 8 by 3 to get:
8 feet / 3 feet/yard = 2.67 yards. However, since we are asked to express the answer in yards and feet, we can state that 8 feet is equal to 2 yards and 2 feet.

Alternatively, if we want to express 8 feet as a decimal, we can divide 8 by 3 to get:
8 feet / 3 feet/yard = 2.67 yards. So, 8 feet is approximately equal to 2.67 yards.
