1. 3 yards 5 feet 6 inches times 7 =?
First, convert to inches:
3 * 36 (in/yd) + 5 * 12 (in/ft) + 6 = 108 + 60 + 6 = 174 inches.
174 * 7 = 1218 in = 33 yd, 2 ft, 6 in
2. 4 yards 2 feet 7 inches+ 2 yards 1 foot 6 inches =?
4 yards + 2 yards = 6 yards
2 feet + 1 feet = 3 feet = 1 yard
7 inches + 6 inches = 13 inches = 1 ft 1 inch
Add it up: 7 yards, 1 foot, 1 inch.
3. 7 days 8 hourse 20 minutes - 4 days 10 hourse 30 minutes= ?
7 days * 24 d/hr * 60 hr/min + 8 hours * 60 hr/min + 20 min = 10580 min.
4 days * 24 d/hr * 60 hr/min + 10 hours * 60 hr/min + 30 min = 6390 min.
10580 - 6390 = 4190 min = 2 days, 21 hours, 50 minutes
4. 5 yards 1 foot divided by 4 =?
5 yards * 3 ft/yard + 1 ft = 16 ft.
16 ft/4 = 4 feet. (solution)
