Answer:
$16875
Step-by-step explanation:
Find the perimeter by adding all the lengths, which is 1875 ft.
Since 3ft = 1 yd, 1875/3 = 625 yds.
$27 per yard gives 625 * 27 = 16875.
Maybe the right two because they are more equal to each other making a better estimate.
1st change 1 5/6 into a mixed number:
1 5/6 = 11/6
New problem:
8/10 divided by 11/6
to divide fractions you turn the 1st fraction upside down and then change the division sign to a multiplication sign:
8/10 / 11/6
10/8 * 11/6
=55/24 or 1 7/24
