What does the equal? keep getting it wrong

You get -9/4. 1/2 divided by 2= 1/4. Then 1/4 times 2 which equals 2. Then 1/4+4. So 1/4 +4/1, you have to turn 4/1 to 16/4 because you need the same denominator to add fractions. 1/4+16/4 equals 17/4. Then you turn 2/1 to 8/4 to subtract the two fractions. So now you have 8/4-17/4 which equals -9/4.
