Question

Change the following mixed number to an improper fraction. Reduce if possible. 7 81/1000

Answer 1

The answer is 7081/1000

Answer 2

Step-by-step explanation:

7 = 7×1 = 7×1000/1000 = 7000/1000

7000/1000 + 81/1000 = 7081/1000

this can't be further simplified, as the only factors of 1000 are

2 and 5 and then multiples of them.

neither of them can be a factor of 7081 (which is clearly neither an even number nor a multiple of 5).
