unit 2 ratio & proportional relationships
Complex Fractions - a fraction where your numerator, denominator, or both contain a fraction. Examples:
Proportional Relationships - when two quantities vary directly with each other. Y = kx, where k is the constant, called the constant of proportionality.

Problem Solving:
Jamie is making bracelets using black and red beads. She uses 6 black beads for every 4 red beads. Represent the number of black beads for any given number of red beads using a table, a graph, and an equation. Identify the constant of proportionality.
The ratio of black beads to red beads will be the same for all quantities.
The ratio of black beads to red beads will be the same for all quantities.
