Answer :

64 inches because there are 1.7778 yards in 64 inches.
1 yard= 3 feet
1 foot= 12 inches
Convert this problem into one like unit of measurement. Use the smallest one. In this case, inches. 
So, convert 1 2/3 yards to inches. 
1 2/3 = 5/3
5/3 * 3(feet) = 15/3 = 5
There are 5 feet in 1 2/3 yards.
Next, convert the five feet to inches. 
5 * 12 = 60
1 2/3 yards represents 60 inches. 
Since 64 is greater than 60, you can say that 64 inches is greater than 1 2/3 yards.
