Answer 1

18 green beads are needed to go with 12 red beads
14 red beads are needed to go with 21 green beads

Answer 2

14 red beads are needed to go with 21 green beads

Step-by-step explanation:

The ratio of the red beads to green beads is 2:3

let the ratio be x

So, Red beads = 2x

Green beads = 3x

We are given that there are 12 red beads

So, 2x = 12

x= 6

Green beads = 3x =3(6)=18

So, 18 green beads are needed to go with 12 red beads

If there are 21 green beads

SO, 3x=21

x=7

Red beads = 2x =2(7)=14

So,14 red beads are needed to go with 21 green beads
