Well you could simplify the fraction(s) in question to their smallest form (where you can’t divide anymore without getting decimal answers) and see if they are equal to 1/4.
For example 2/8, you can divide both sides by 2 to simplify to 1/4, thus 2/8 is equivalent to 1/4.
Hope this helps!
1. m<13
2. y>2
3. p>-3
I don't know the answers for the last two
In a fraction, the number below the line (called the denominator) represent the whole. In this problem '8' is in the denominator and represents the 8 slices of pizza there were to start with
Answer=8 slices
You can turn 5 into 10/2 and add to x/2
then you need to use simple algebra to left the x alone in the equation so you need to multiply both sides by 2 so you get
2y=10+x
then you need to subtract both sides a 10 so
2y-10=x
now change the x to f'(x) and y to x so:
f'(x)=2x-10
