Question

I'm I doing this right?

Answer 1

If 2000 uS/cm = 1000 mg/L
then 1180 uS/cm = 1.18 mg/L right ?

Answer 2

@Hero

Answer 3

\(\dfrac{2000uS/cm}{1000mg/L}=\dfrac{1180uS/cm}{xmg/L}\)

you can multiply both sides by x and both sides by 1000

Answer 4

2000x=1180*1000

solve for x

Answer 5

590 got it

Answer 6

also worth noting, the ratio on the left is 2:1

that is, the top is twice as much as the bottom

Answer 7

so 1180/2=590

Answer 8

oh that's true, thanks !
