Answer 1

To determine which proportion correctly describes the relative amounts of each color of blocks from the two groups of children, we need to examine the ratio of red blocks to green blocks in each group.

For the first group:

• Red blocks = 15
• Green blocks = 45
• The ratio of red to green is: \[ \frac{15}{45} = \frac{1}{3} \]

For the second group:

• Red blocks = 30
• Green blocks = 90
• The ratio of red to green is: \[ \frac{30}{90} = \frac{1}{3} \]

Now we can compare the two ratios:

• The ratio of red to green blocks in both groups is \(\frac{1}{3}\).

The correct proportions from the options provided that describe the relative amounts of each color are: \[ \frac{15}{45} = \frac{30}{90} \] Which simplifies to: \[ \frac{1}{3} = \frac{1}{3} \] Thus, the most appropriate choice would be:

1545 = 3090

This indicates that the ratios of red to green blocks are equivalent for both groups.
