Question

solve b/k=n for k

Answer 1

the solution must

k = whatever

Answer 2

you have

b/k=n for k

b
--- = n
k

how do you get

k

Answer 3

b*n?

Answer 4

what do you get then?

Answer 5

k

Answer 6

there are other things you are able to use

such as multiplying by the

reciprocal

Answer 7

b
b [ --- = n ]
k

b
n [ --- = n ]
k

if you multiply by
b or n

you will get

b^2
--- =bn
k

bn
--- = n^2
k

Answer 8

neither can you multiply it by
b * n

Answer 9

you want to get

"k" on 1 side only

but what ever operation that is performed on 1 side of the equation
" must be performed on the other"

Answer 10

k=?

Answer 11

there are no
numbers being used here

Answer 12

just moving things around

Answer 13

b*n^2 or something like that right

Answer 14

have you tried reciprocals?

Answer 15

EXAMPLE

A
C= ---
B

SOLVE FOR B

A B 1
B [ C = --- ] MULTIPLY ---
B B

CROSS CANCEL GIVES ME


BC = A NOW I JUST NEED TO DIVIDE

1
--- [ B C = A ] MULTIPLY BY RECIPROCAL SAME AS DIVIDING
C

THIS GIVES

A
B = ---
C

Answer 16

does this clear much stuff up or no?

Answer 17

k = N/B

Answer 18

well almost but your original equation was

b / k = n

Answer 19

so you got
k
on one side by multiply by the reciprocal

Answer 20

b=nk

Answer 21

ok now try that

Answer 22

k=b/n

Answer 23

yep

Answer 24

but
now the only the only thing is
do you understand how you got the answer?

Answer 25

Yes thank you. I was not dividing right. I always look at things backwards

Answer 26
