Answer:
Proper fraction
Step-by-step explanation:
If the numerator is less than the denominator , then it is proper fraction.
Example : 
You should first write out the equations,
perimeter= 3/y-4+3/y-4+1/y+1/y, and the area is 3/y-4•1/y
then you can simplify it.
Answer:
b) in the vertex.
Step-by-step explanation:
In the vertex. If the parabola opens up or down the axis of symmetry is x = a where a is the x coordinate of the vertex.

First, convert the decimals into improper fractions. The fractions are:
31/10 and 10261/1000. To divide the fractions, change division into multiplication after flipping the numerator and the denominator of the second fraction. This comes out to be 31/10 *(times) 1000/10261.
31*1000 is 31,000 and 10*10261 is 102,610. This equals the fraction: 31,000/102,610. Simplify this.
