17000 ÷ 100 = 170
170 × 15 = 2550
You basically multiply across. 1/4 times 7/8 is 7/32 because numerator, 1 times 7 and denominator, 4 times 8. Hope it helps.

The best and most correct answer among the choices provided by your question is the fourth choice or letter D. The probability is 4/5.
<span>P ( canadian)= 3/15 = 1/5
On the other hand, P (not canadian) = 1 - 1/5 = 4/5</span>
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
So you only have 3 sides so the perimeter will be length+2width instead of 2length+2 width
l+2w= perimeter
you know the length of the longest side is 15
15+2w = perimeter
and you also know that he is using 31 feet of fencing
15+2w = 31
2w = 16
w=8
