Answer:
500 beads
Step-by-step explanation:
Let x = the total amount of beads
Since 27% of the beads are red, we just have to multiply x by 0.27 to get the amount of red beads, which is 135
0.27x = 135
To isolate the x variable, just divide both sides by 0.27
0.27x/0.27 = 135/0.27
x = 500
The total amount of beads is equal to 500
