The rule to convert a mixed fraction to an improper fraction is

Here in 
Here a = 422, b = 8 and c = 100
Now a × c = 422 × 100 = 42200
And 42200 + 8 = 42208
So we have

This fraction can also be reduced as

Hence

72 is a number that can divide into 8 and by 9 also
Area is equal to length times width, so 1.3x would represent the area. B is the answer.
Answer:
cscθ = 
Step-by-step explanation:
cscθ = 
For a unit circle, radius = 1
hence, hypotenuse = 1
opposite = y
cscθ =
