Answer:
1. The red one
2. 60%
3. 18,57%
Step-by-step explanation:
I use the way to calculate the percentage in question 2 and 3
2. (6:10)x100%
3. (13:7)x100%
Division of a fraction is the equivalent of multiplying by its reciprocal
ex.
![\frac{\frac{A}{B} }{\frac{C}{D}}=\frac{A}{B} *\frac{D}{C}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7BA%7D%7BB%7D%20%7D%7B%5Cfrac%7BC%7D%7BD%7D%7D%3D%5Cfrac%7BA%7D%7BB%7D%20%2A%5Cfrac%7BD%7D%7BC%7D)
i suggest you try to remember this concept
in terms of your question
from this point, just multiple the numerators together and denominators together, then simplify if necessary
fyi- difference of squares
![x^2-b^2 = (x-b)(x+b)](https://tex.z-dn.net/?f=x%5E2-b%5E2%20%3D%20%28x-b%29%28x%2Bb%29)
relating that to
![c^2-4 = c^2 -2^2 = (c-2)(c+2)](https://tex.z-dn.net/?f=c%5E2-4%20%3D%20c%5E2%20-2%5E2%20%3D%20%28c-2%29%28c%2B2%29)
also a side note, you might want to factor out the 4 first in the top fraction
Answer:
depends on the number of available jobs
An expression that is equivalent to
is ![13^{\frac{3}{5}](https://tex.z-dn.net/?f=%2013%5E%7B%5Cfrac%7B3%7D%7B5%7D%20%20)
