The correct Answer is:
To solve the problem of finding the ratio of the words starting with T and ending with E to the words ending with G using the letters of the word "TRIANGLE," we will follow these steps: ### Step 1: Identify the letters in the word "TRIANGLE" The word "TRIANGLE" consists of 8 letters: T, R, I, A, N, G, L, E. ### Step 2: Calculate the number of words starting with T and ending with E When we fix T at the beginning and E at the end, we have the following letters left to arrange: R, I, A, N, G, L (6 letters). The number of ways to arrange these 6 letters is given by \(6!\) (6 factorial). \[ 6! = 720 \] ### Step 3: Calculate the number of words ending with G When we fix G at the end, we have the following letters left to arrange: T, R, I, A, N, L, E (7 letters). The number of ways to arrange these 7 letters is given by \(7!\) (7 factorial). \[ 7! = 5040 \] ### Step 4: Form the ratio Now, we need to find the ratio of the number of words starting with T and ending with E to the number of words ending with G. The ratio can be expressed as: \[ \text{Ratio} = \frac{6!}{7!} \] ### Step 5: Simplify the ratio Using the property of factorials, we know that \(7! = 7 \times 6!\). Thus, we can simplify the ratio: \[ \text{Ratio} = \frac{6!}{7 \times 6!} = \frac{1}{7} \] ### Conclusion The ratio of the words starting with T and ending with E to the words ending with G is: \[ 1 : 7 \]
