@jim_thompson5910 could u help?

Answer 12

okay, thanks anyway:(

Answer 13

Let's say we had a car going `30 miles` in `2 hours`

the unit rate would be 15 miles per hour since

(30 miles)/(2 hours) = (15 miles)/(1 hour)

notice how I divided both parts by 2

Answer 14

it's called "unit rate" because the denominator has 1 unit (in my example, it's 1 hour)

Answer 15

Instead of saying, "I'm confused," would you please ask questions? This could be one way in which you'd reach a better understanding of these problems.

"I'm confused" puts the entire burden of explanation in someone else's lap, which is neither fair nor helpful to you in the long run.

Answer 16

does my example make sense @K12awesomeness ?

Answer 17

What's a ratio: Define it and give examples.

Write the ratio of the number of white cars to the number of red cars. Simplify, so that the denominator is "1 red car."

Answer 27

thx

Answer 28

Do I divide 30 and 12 ?

Answer 29

yes you type in `30/12`

Answer 30

okay, then I would get... 2.5 or 2 1/2

Answer 31

2.5 is correct

Answer 32

so `30 white cars for every 12 red cars` is the same as saying `2.5 white cars for every 1 red car`

Answer 33

does that make sense?

So it's B

correct

Okay, Thank!!
