To determine the proportion of red blocks to green blocks in each group, we can start by analyzing the two groups separately.
Group 1:
- Red blocks: 10
- Green blocks: 30
The total number of blocks in Group 1 is: \[ 10 + 30 = 40 \]
The proportion of red to green blocks in Group 1 is:
- Red proportion: \( \frac{10}{40} = \frac{1}{4} \)
- Green proportion: \( \frac{30}{40} = \frac{3}{4} \)
Group 2:
- Red blocks: 20
- Green blocks: 60
The total number of blocks in Group 2 is: \[ 20 + 60 = 80 \]
The proportion of red to green blocks in Group 2 is:
- Red proportion: \( \frac{20}{80} = \frac{1}{4} \)
- Green proportion: \( \frac{60}{80} = \frac{3}{4} \)
Summary of Proportions: For both groups:
- The proportion of red blocks is \( \frac{1}{4} \).
- The proportion of green blocks is \( \frac{3}{4} \).
Therefore, the relative amounts of each color can be described by the proportions \( \frac{1}{4} \) (red) and \( \frac{3}{4} \) (green) for both groups.
