Answer:
I don't know but I can help you understand it.
Step-by-step explanation:
First find the the answer to the problem and then try to compare all of them to each other and choose the one that makes the most sense.
40 meters in 60 seconds could be expressed as

So, in order to get the unit rate, we divide the numerator and denominator by 16.

So, the unit rate is 2.5 meters per second (or every one second)
All you have to do is understand what fraction it is and reduce it. So first you have to figure out what the word reduce means and the word means another to figuring it out in its lowest terms and for example, your fraction 2/24 can be reduced in its simplest terms 1/12 and the way i did that was that i'd had to divide both the numerator and denominator by 2 because I know that both the numerator and denominator are divisible by 2 and so if you divide you get 1/16 and that's how you reduce fractions and so follow this procedure and you'll get everything correct.
