Answer:
<em>The fraction of the beads that are red is</em>
Step-by-step explanation:
<u>Algebraic Expressions</u>
A bag contains red (r), yellow (y), and blue (b) beads. We are given the following ratios:
r:y = 2:3
y:b = 5:4
We are required to find r:s, where s is the total of beads in the bag, or
s = r + y + b
Thus, we need to calculate:
Knowing that:
Multiplying the equations above:
Simplifying:
Dividing [1] by r:
Substituting from [2] and [3]:
Operating:
The fraction of the beads that are red is
