Analyze scalar multiplication

Vector v=(x,y)\vec v=(x,y) and v=10||\vec v||= 10.
Fill in the blanks to complete the following sentences.
Vector w=(15x,15y)\vec w=\left(\dfrac{1}{5}x,\dfrac{1}{5}y\right), so w=||\vec w||=
  • Your answer should be
  • an integer, like 66
  • a simplified proper fraction, like 3/53/5
  • a simplified improper fraction, like 7/47/4
  • a mixed number, like 1 3/41\ 3/4
  • an exact decimal, like 0.750.75
  • a multiple of pi, like 12 pi12\ \text{pi} or 2/3 pi2/3\ \text{pi}
.
Vector z=(35x,35y)\vec z=\left(\dfrac{3}{5}x,\dfrac{3}{5}y\right), so z=||\vec z||=
  • Your answer should be
  • an integer, like 66
  • a simplified proper fraction, like 3/53/5
  • a simplified improper fraction, like 7/47/4
  • a mixed number, like 1 3/41\ 3/4
  • an exact decimal, like 0.750.75
  • a multiple of pi, like 12 pi12\ \text{pi} or 2/3 pi2/3\ \text{pi}
.
Match each vector defined above to a vector that could be its equivalent.
  • v\vec v
  • w\vec w
  • z\vec z
