It is arranged according to the exponents so this should be t
If you divide 84 red beads and 4 red beads you will get 21 red beads. When you divide 133 gold beads and 19 gold beads you will get 7 gold beads. So the ratio would be 21 red beads/ 7 gold beads.
equation: 84÷ 4= 21 red beads
133÷ 19= 7 gold beads
( If you were to go a bit deeper into the equation, when you simplify this ratio it will bring you to the solution of 3)
