fractions:
Fraction is a part of a whole, for example 1/2. Equivalent fractions are fractions that look different but show the same amount. Improper fractions have numerators that are higher than the denominator, while mixed fractions contain whole numbers and fractions.
In order to compare fractions, you need to change them so they have the same denominator. Fractions can be converted into decimals. You need to be able to work out a fraction of a given quantity.

How do we find 3/5 of 20?
Method 1 is to find 1/5 of 20, then multiply by 3.
1/5 of 20 is 20 ÷ 5 = 4.
We need 3/5 of 20, so we multiply 4 by 3.
3/5 of 20 = 4 × 3 = 12.
you can put this in your calculator:
3/5<span> × 20 = </span>3/5<span> × </span>20/1<span> = </span>60/5<span> = 12</span>

Answer:
<h3>The answer is 4x</h3>
Step-by-step explanation:
![({64 {x}^{3} })^{ \frac{1}{3} }](https://tex.z-dn.net/?f=%20%28%7B64%20%7Bx%7D%5E%7B3%7D%20%7D%29%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20)
To solve the expression convert 64 to exponential form
That's
64 = 4³
So we have
![( { {4}^{3} {x}^{3} })^{ \frac{1}{3} }](https://tex.z-dn.net/?f=%28%20%7B%20%7B4%7D%5E%7B3%7D%20%20%7Bx%7D%5E%7B3%7D%20%7D%29%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20)
Using the rules of indices
That's
![( { {a}^{x} {b}^{y} })^{z} = {a}^{x \times z} . {b}^{y \times z}](https://tex.z-dn.net/?f=%28%20%7B%20%7Ba%7D%5E%7Bx%7D%20%7Bb%7D%5E%7By%7D%20%20%7D%29%5E%7Bz%7D%20%20%3D%20%20%7Ba%7D%5E%7Bx%20%5Ctimes%20z%7D%20.%20%7Bb%7D%5E%7By%20%5Ctimes%20z%7D%20)
So for the above expression we have
![( { {4}^{3} {x}^{3} })^{ \frac{1}{3} } = {4}^{3 \times \frac{1}{3} } . {x}^{3 \times \frac{1}{3} }](https://tex.z-dn.net/?f=%28%20%7B%20%7B4%7D%5E%7B3%7D%20%20%7Bx%7D%5E%7B3%7D%20%7D%29%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20%20%3D%20%20%7B4%7D%5E%7B3%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20.%20%7Bx%7D%5E%7B3%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20)
Simplify the expression
We have the final answer as
<h3>4x</h3>
