PLEASE HELP WITH TWO ALGEBRA PROBLEMS FOR MEDALS!!!!

QUESTION 1:
In a classroom, 11 out of 17 students surveyed say they had two or more siblings. If the entire school has 850 students, predict the number of students that have two or more siblings.

___ students

QUESTION 2:
The ratio of the perimeters of two rectangles is 4 to 9. If the perimeter of the larger rectangle is 54 inches, what is the perimeter of the smaller rectangle?

____ inches

Answer 1

well the first one is almost exactly like the other one i helped you with. maybe you could do that one on your own?

Answer 2

\[\frac{ 11 }{ 17 }=\frac{ x }{ 850 }\]
then,
17x = 11 x 850
17x = 9350
9350 divded by 17 is 550

Answer 3

yep

Answer 4

ok i think i got the next one :) do you want a medal?

Answer 5

yess :3
you wanna post your answer and i'll tell you if you got it right?

Answer 6

Okay here it is,
\[\frac{ 4 }{ 9 }=\frac{ x }{ 54 }\]
then I used cross multiplication,
9x = 4 x 54
9x = 216
216 dvided by 9 is 24
is that right?
