Answer:
See explanation.
Step-by-step explanation:
It is subtraction
whole numbers, then numerators.
6 - 2 = 4
1/2 - 3/8
= 4/8 - 3/8 (1/2 = 4/8)
= 1/8
= 4 1/8
hope this helps!

By definition, the unit vector of v = (a,b) is

Therefore,
The unit vector of v₁ = (3,5) in the direction of |v₁| s
 (3,5)/√[3² + 5²]
= (3,5)/√34
The unit vector of v₂ in the direction of |v₂| is
(-4,7)/√[(-4)² + 7²]
= (-4,7)/√65
Answer:
The unit vector of v₁ in the direction of |v₁} is 

The unit vector of v₂ in the directin of |v₂| is
