Answer:
B. 6 1/4
Step-by-step explanation:
The computation of the more flour Nicholas needed for making the cake and cookies is shown below:

= 11.75 - 5.50
= 6.25 more cups of flour
Therefore to make the cookies and cakes, 6.25 more cups of flour is required or needed and the same is to be considered
hence, the correct option is B. 6 1/4
Is this even a question? its 66/100 you always use the first examining over 100.... makes sense
Lets just use

for an example. If the number is increased by 60% and the denominator is decreased by 20% we get the new fraction being:

. Since then new one is equal to 1, and the original is equal to

, we see that this manipulation of the fraction causes an increase of 100%.
According to the triangle inequality theorem a+b > c
so a+b is greater.
Hope it helps!
