Final answer:
The ratio of stars to hearts to circles that Ella drew is 1:1:2.25, as she drew 8 stars, 8 hearts, and 18 circles. The ratio is simplified and does not match any of the given answer choices.
Step-by-step explanation:
The question asks us to determine the ratio of stars to hearts to circles that Ella drew. Ella drew 8 hearts, 8 stars, and 18 circles. To express the ratio, we simply write the numbers in the same order as the shapes are mentioned, and separate them by colons.
The number of hearts Ella drew is 8, the number of stars is also 8, and the number of circles is 18. To simplify the ratio, we need to find a common factor if possible. Here, it's clear that the common factor for 8 and 8 is 8 itself, but 18 does not share this factor. So, the ratio of stars to hearts to circles is simply 1:1:2.25. However, since we usually express ratios in whole numbers, we need to scale up the ratio so that the smallest value in the ratio is 1 (we cannot do this while keeping all numbers whole in this case), and the other numbers are in proportion. To maintain the ratio without decimal or fractional values, we can multiply each part by 4 (since 18 divided by 8 is approximately 2.25 and multiplied by 4 is 9, which is a whole number), getting 4:4:9, which simplifies to 1:1:2.25, which doesn't match any of the answer choices provided.
