I found a pile of string on the ground. The pieces are 18 inches long, 24 inches long, two and a half feet long and 4 yards long. How many YARDS of string do I have in TOTAL?
6 Yards
--18 inches=1 and 1/2 feet
--24 inches=2 feet
--2 1/2 feet=2 1/2 feet
TOTAL=6 feet
--3 feet/yard=2 YARDS
4+2=6 YARDS
