Rates and Measurement Unit Test 2 of 152 of 15 Items Question 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 13 Start Fraction 1 over 3 End Fraction 1545 Start Fraction 15 over 45 Endfraction 1545 = 9030 Startfraction 15 over 45 End Fraction equals Start Fraction 90 over 30 End Fraction 1545 = 3090

Answer 1

The correct proportion that describes the relative amounts of each color is:

15 red blocks : 45 green blocks

This can be written as:

15/45 = 1/3.

Answer 2

To determine the correct proportion that describes the relative amounts of each color, we need to compare the number of red blocks to the number of green blocks in each group.

Group 1 has 15 red blocks and 45 green blocks, so the proportion is:

Start Fraction 15 over 45 End Fraction

Group 2 has 30 red blocks and 90 green blocks, so the proportion is:

Start Fraction 30 over 90 End Fraction

Therefore, the correct proportion is:

Start Fraction 15 over 45 End Fraction = Start Fraction 30 over 90 End Fraction

Answer 3

To determine the correct proportion that describes the relative amounts of each color, we need to compare the number of red blocks to the number of green blocks in each group.

In the first group, there are 15 red blocks and 45 green blocks. So, the ratio of red to green blocks in the first group is 15:45.

In the second group, there are 30 red blocks and 90 green blocks. So, the ratio of red to green blocks in the second group is 30:90.

To simplify the ratios, we can divide the number of blocks by their greatest common divisor. In this case, both ratios can be simplified by dividing by 15.

For the first group, 15 ÷ 15 = 1 and 45 ÷ 15 = 3. So, the simplified ratio for the first group is 1:3.

For the second group, 30 ÷ 15 = 2 and 90 ÷ 15 = 6. So, the simplified ratio for the second group is 2:6, which can be further simplified to 1:3 as well.

Therefore, the correct proportion that describes the relative amounts of each color is 1:3.
