Answer:

Correct choices: a) 5:12 and c) 7 to 12

Step-by-step explanation:

The ratio of red beads to pink beads is 5:7. This means that for every 5 red beads there are 7 pink beads.

It also means that for every 12 beads there are 5 red beads and 7 pink beads.

Therefore, there are two part-to-whole ratios:

5:12 red beans to total beads, and

7:12 pink beans to total beads

Correct choices: a) 5:12 and c) 7 to 12
