In a classroom, 5 out of 13 students surveyed said they had two or more siblings. If the entire school has 520 students, predict the number of students that have two or more siblings. Write a proportion to model the problem. Use x for your variable.

Answer 1

Is it a written answer or is it a multiple choice

Answer 2

it is a written answer question @mayekeroom

Answer 3

ok so you have to use a proportion\[\frac{ part }{ whole }\frac{ 5 }{ 13 }=\frac{ x }{ 520 }\]

Answer 4

cross-multiply and solve for x

Answer 5

i don't really know how to do that?

Answer 6

5(520) = 13x

Answer 7

see what i did?

Answer 8

after I solve 5 times 520 I divide both sides by 13?

Answer 9

yes

Answer 10

it's 200

Answer 11

yep

Answer 12

so the written proportion is \[\frac{ 5 }{ 13 }=\frac{ x }{ 520}\]

Answer 13

yes
