Answer 1

Step-by-step explanation:

the ratio of black and white beads=3:5

the ratio of white and red =2:3

White: black:red

3:5

2:3

therefore, according to the properties of ratio, we get

the ratio of the three beads black, white and red as,

= [3*2] : [5*2] : [5*3]

= 6 : 10 : 15

thus the ratio of three beads is 6 : 10 : 15
