To determine the correct proportion that describes the relative amounts of each color, let's simplify the ratios for both groups of children.

For the first group:

  • Red blocks: 15
  • Green blocks: 45

The ratio of red to green for the first group simplifies to: \[ \frac{15}{45} = \frac{1}{3} \]

For the second group:

  • Red blocks: 30
  • Green blocks: 90

The ratio of red to green for the second group simplifies to: \[ \frac{30}{90} = \frac{1}{3} \]

Both groups have the same ratio of red to green blocks, which is \( \frac{1}{3} \).

Now looking at the options, the correct proportions are:

  • \( \frac{15}{45} = \frac{30}{90} \)
  • \( \frac{15}{45} \) simplifies to \( \frac{1}{3} \)

So the correct response is: \[ \frac{15}{45} = \frac{30}{90} \]

This option states the relation between the proportions clearly.
