Answer:
C, D and E
Step-by-step explanation:
Given
Represent solid beads with S and clear beads with C
So:

Required
Select operations that give an equivalent ratio
First, we need to get the unit ratio

Divide through by 4
-- This means that, after any operation. The equivalent ratio must be 2: 5
Option A: Add 2 to S and 2 to C

Perform the operation


Divide through by 2

Option B: Subtract 8 from S and 6 from C

Perform the operation


Option C: Multiply S and C by 2

Perform the operation


Divide through by 8

Option D: Divide S and C by 4

Perform the operation


Option E: Multiply S and C by 18

Perform the operation


Divide through by 72


<em>From the calculations above, options C, D and E gave an equivalent of 2:5.</em>
The second option is your answer.
2(1) - 3 = 2 - 3 = - 1
2(2) - 3 = 4 - 3 = 1
2(3) - 3 = 6 - 3 = 3
2(4) - 3 = 8 - 3 = 5
- 1 + 1 + 3 + 5 = 8
True ........... I Hope this helps you answer your question.
