2/3 ÷ (-5/6)
When dividing fractions, all you really have to do is multiply the first fraction by the second fraction's reciprocal.
Remember, a reciprocal is the fraction/whole number flipped.
Ex : 4/6 turns into 6/4
So, the reciprocal of -5/6 is -6/5
Therefore, our new equation looks like this :
2/3 × -6/5
Multiply the numerators with the numerators, and the denominators with the denominators :)
Numerators : 2 × -6 = -12
Denominators : 3 × 5 = 15
SO, our answer is -12/15
Simplify this.
-4/5

Answer:
meters
Step-by-step explanation:
Aka M is larger than mm. A millimeter(mm) is the smallest common metric unit of length.
Answer:
18
Step-by-step explanation:
w varies directly with z, let k be the constant of proportionality, hence this can be represented by the equation:
w = kz
When z = 4, w = 12, hence we need to find the value of the constant of proportionality, substituting:
12 = 4k
Dividing both sides by 4:
12/4 = 4k/4
k = 3
Therefore the equation becomes:
w = 3z
The value of w when z = 6 is given as:
w = 3(6)
w = 18
