How would you express the mixed number 2 1/5 as an improper fraction?

11/5
10/5
1/5
12/5

The correct answer is: 11/5

To convert the mixed number 2 1/5 into an improper fraction, you start by multiplying the whole number part by the denominator of the fractional part. In this case, the whole number is 2 and the fractional part is 1/5. First, multiply 2 (the whole number) by 5 (the denominator): 2 × 5 = 10. Next, take this result and add the numerator of the fractional part, which is 1. So, you add 10 and 1: 10 + 1 = 11. This total becomes the numerator of the improper fraction, while the denominator remains the same (which is 5). Therefore, the improper fraction representation of the mixed number 2 1/5 is 11/5. This method ensures that you maintain the value of the original mixed number while presenting it in an improper fraction form.
