One group of children has 15 red blocks and 45 green blocks. Another group of children has 30 red blocks and 90 green blocks. Which proportion correctly describes the relative amounts of each color?(1 point)
Responses
1545
Start Fraction 15 over 45 End Fraction
1545 = 9030
Start Fraction 15 over 45 End Fraction equals Start Fraction 90 over 30 End Fraction
1545 = 3090
Start Fraction 15 over 45 End Fraction equals Start Fraction 30 over 90 End Fraction
13
Start Fraction 1 over 3 End Fraction
15/45 = 30/90 = 1/3
you really need to learn how to type fractions.
is the answer 15/45, 30/90 or 1/3?
About 4,000 new species of marine animals were discovered in the last 2 years. What is the unit rate of discovery A, 2 years/4,000 B, species 1 species/2,000 years C, 4,000 species/2 years 2,000 species
D, 2,000 species/ year

The correct anwer is:
15/45=30/90
The correct proportion that describes the relative amounts of each color is:
Start Fraction 15 over 45 End Fraction
To explain how to get this answer, we need to determine the ratio of red blocks to green blocks for each group separately.
For the first group, the ratio of red blocks to green blocks is 15:45, which simplifies to 1:3.
For the second group, the ratio of red blocks to green blocks is 30:90, which also simplifies to 1:3.
Therefore, both groups have the same ratio of red blocks to green blocks, which is 1:3.
So, the correct proportion is Start Fraction 15 over 45 End Fraction, which represents the relative amounts of each color.
