You don't simplify rational numbers, but sometimes you can simplify a fraction.
The way to do that is to divide the top and bottom by their greatest common factor.
The greatest common factor of 57 and 69 is 3 . When you divide the top and
bottom by 3 , you have 19/23 . That's the simplest form of that particular fraction.
Answer:
5) distributive property
7) Transitive property
8) Associative property

Answer:
b = 125
Step-by-step explanation:
Given a varies directly as ![\sqrt[3]{b}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bb%7D)
then the equation relating them is
a = k ← k is the constant of variation
To find k use the condition a = 3 , b = 64 , then
3 = k![\sqrt[3]{64}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D)
= 4k ( divide both sides by 4 )
= k
a = ← equation of variation
When a = 
, then
= ( multiply both sides by 4 to clear the fractions )
15 = 3 ( divide both sides by 3 )
5 = , then
b = 5³ = 125
