Question

What is the value of n?

4/5 < n/7 < 8/9
( n has to be greater than 4 but less than 8 )​

Answer 1

n = 6

Explanation:

If n/7 < 8/9, then n/7 < 1

n/7 < 1

n < 7

That leaves us with 5 and 6. With this, we use trial and error.

4/5 > 5/7 (not we want)

4/5 < 6/7 (what we want)

The answer is 6/7 or n = 6
