Question

In writing the ratio of measurement numbers, the units must be the same.

True
False

Answer 1

Think with me... A ratio is a unitless number... So now give me the answer

Answer 2

False?

Answer 3

how do you get a unitless number?

let's say 30 Newtons and 15 Newtons

if you devide both you'll have

\[\frac{ 30 }{ 15 } \times \frac{ Newton }{ Newton } = 2\]

unitless

Answer 4

I kinda still don't get it.

Answer 5

When you devide 2 things that are the same the answer is 1

so when you devide Newton by Newton (force measure) you'll get 1

That's why 30 N / 15 N = (30/15) * (N/N) , where (N/N) = 1
so the answer is just 30/15 = 2
