<u>Step-by-step explanation:</u>
We are given a number of incomplete fractions and we are to find the missing numerator in each one of these.
To find the missing numerator or denominator, we multiply the numerator and the denominator by the same number to get an equivalent fraction.
A. 
Here the denominator is multiplied by 2 so the denominator will also be multiplied by 2 to get 10.

Answer:
90°
Step-by-step explanation:
Circle C has radius √36 = 6
Circle D has radius √18 = 3√2
As the D radius intersecting either point of tangency, does so at a right angle.
The half angle θ between the tangents is
sinθ = 3√2 / 6 = ½√2
θ = 45°
so the angle between the tangents is 2(45) = 90°
