7) Im not sure on this one
8) x = 5

95 because if you do the math you’ll get the answer
Your answer is d

To be able to compare 2 fraciton we have to make common denominator and then we can just compare numerators.

Now we can compare numerator from the first (9) and from the second fraction (8)
9>8, so the bigger is 9/10
