Explain how complex fractions can be used to solve problems involving ratios

So when you have ratios, some are unknowns you have to create complex fractions from them. Bring to the same donominator, and solve for x.

Ex: we have this portion:
2 -x
5-45

and we change it into fractions 

2/5 =x/25

2x9/5x9 = x/45

answer would be 18=x

in case of more  complex fractions it may become in handy.

t <

Step-by-step explanation:

Add '5t' to both sides

12t - 2 +5t < -5t +36 +5t

17t -2 < 36

Add ' 2' to both sides  

17t -2 +2 < 36 + 2

17t < 38

Dividing '17' on both sides
