To convert the mixed number 1 7/8 to an improper fraction, you need to multiply the whole number by the denominator of the fraction and add the numerator. Here's the step-by-step calculation:

1 * 8 = 8
8 + 7 = 15

Therefore, the mixed number 1 7/8 as an improper fraction greater than 1 is 15/8.

So, the correct answer is: 15/8

To convert the mixed number, 1 7/8, into a fraction greater than 1, you need to first convert the whole number and the fraction into improper fractions. Here's how:

1) Convert the whole number, 1, into an improper fraction by multiplying it by the denominator of the fraction, which is 8.

1 x 8 = 8

Therefore, the improper fraction for the whole number 1 is 8/8.

2) Keep the denominator the same as 8, and add the numerator of the original fraction, which is 7, to the numerator of the improper fraction obtained in step 1.

8/8 + 7/8 = (8 + 7)/8 = 15/8

So, the mixed number 1 7/8 is equivalent to the improper fraction 15/8.

Now, looking at the given options:
1) 9/8 - This is less than 1
2) 15/8 - This is the correct answer as we just converted the mixed number to this fraction.
3) 16/8 - This is equivalent to 2, which is greater than 1, but it does not match the converted fraction.
4) 17/8 - This is greater than 1, but it does not match the converted fraction.

Therefore, the correct answer is 15/8.
