Step-by-step explanation: To write the ratio of apples to bananas, we can use the format "apples: bananas."
Here are three different ways to write the 4 ratio of apples to bananas:
1. 4:10 - This ratio represents the number of apples to bananas. In this case, Luis brought 4 apples and 10 bananas.
2. 2:5 - This ratio represents the simplified form of the previous ratio. To simplify the ratio, we divide the numerator (4) and the denominator (10) by their most significant common factor, 2.
3. 40% - This ratio represents the proportion of apples to the total number of fruits Luis brought. To find this ratio, we divide the number of apples (4) by the total number of fruits (10 + 4 = 14) and multiply by 100 to express it as a percentage. In this case, the proportion of apples to the total number of fruits is 4/14, which simplifies to 2/7 or approximately 0.2857. When multiplied by 100, it equals approximately 28.57%, which can be rounded to 40%.
These three ways of writing the 4 ratio of apples to bananas provide different perspectives on the relationship between the number of apples and bananas in Luis's grocery purchase.
