Answer:
2yds 33 in
Explanation:
Convert everything to the lowest unit(inches) perform the operation and convert back
1 yard = 3 feet
1 foot = 12 in
1 yard = 3feet x 12in = 36 in
19yd, 28in = 19 x 36 + 28 = 684 + 28 = 712 in
16yd, 31 in= 16 x 36 + 31 = 576 + 31 = 607 inches
19yd, 28in - 16yd, 31 in = 712 - 607 = 105 inches
Divide by 36 to get the whole number of yards as quotient
105/36 with remainder of 33
∴ 19yd, 28in - 16yd, 31 in = 105 inches = 2yds 33 inches
We can verify this by converting 2yds 11inches to inches and seeing the values agree
2 yds 33 in = 2 x 36 + 33 = 105
