Answer 1

your denominator will be \(55+80+110+40+15\)

Answer 2

how do i find out what my numerator is?

Answer 3

i get the nice round number \(300\)

Answer 4

you are given the numerators in the problem
for example, the number who walk: \(55\) so as a fraction of the total it is
\[\frac{55}{300}=\frac{11}{60}\]

Answer 5

but why is the numerator 55 instead of one of the other numbers?

Answer 6

and for the number who bike it is
\[\frac{80}{300}=\frac{4}{15}\]
oh i see your confusion
you have to do them all

Answer 7

you have to write all of them as fractions, not just one

Answer 8

"write the number of students IN EACH CATEGORY ..."

Answer 9

so you need 5 fractions all together for the first part of the problem
you good with the second part? again you will need 5 numbers

Answer 10

oh i get it now and can you explain how you got 11/60 and 4/15? sorry im really bad at math

Answer 11

no problem

Answer 12

\[\frac{55}{300}=\frac{5\times 11}{5\times 60}=\frac{\cancel{5}\times 11}{\cancel 5\times 60}=\frac{11}{60}\]

Answer 13

also
\[\frac{80}{300}=\frac{8\cancel0}{30\cancel0}=\frac{8}{30}=\frac{4}{15}\]]

Answer 14

this will make the second part of the problem much easier

Answer 15

yes but how did you find out what numbers to multiply 5 with?

Answer 16

it is pretty clear that 5 goes in to 55 evenly right?

Answer 17

and it should be also clear that 5 goes in to 300 because it ends in a zero

Answer 18

so really i just divided top and bottom of \(\frac{55}{300}\) by \(5\) and got \(\frac{11}{60}\)

Answer 19

oh ok thankyou

Answer 20

how about the next part? you okay with that? you have five more numbers to find after the top five

Answer 21

yes im fine i get it now :)

Answer 22

k good
