only answer if you know for sure
~ shwo work by the way~

Question The Not First One
20 sharpened to ?unsharpened and the total is 36
20+X=36
subtract 20 from both sides
X=16
the ratio is 
20:16 
or 
5:4 (D)

Question The Other One

The ratio is
1/6 (pistachios) to 1/3 (almonds) to 1/2 (cashews)
Batch 1
1 (pistachios) 2 (Almonds) ?
? P, 2/3 A, 1 C
4/3 P, ?A, ?C

First, I will find the total amount for all of them

Batch 1- 1 is 1/6 of the full thing so the full thing is 6
Batch 2- 1 is 1/2 if the full so the full is 2
Batch 3- 4/6 is 1/6 of the totals amount so the full is 4

Batch 1- The answer is 3
Batch 2- The answer is 1/3 or 2/6
Batch 3 Almonds- 1  1/3
Batch 3 Cashews- 2

Pistachios make up 

almonds make up 

cashews make up 

Batch 1:

1 cup in pistachios( (which is 1/6) which means there are 5 other cups )and 2 cups in almonds so that leaves  left so the answer is 3 cashews

Answer=3 cups of cashews 

-----------------------------------------------------

Batch 2:

1 cup of cashews which makes up or  of the batch and there are of a cup of almonds so that leaves only  as the only option left

Answer=  of pistachios

----------------------------------------------------

Batch 3:

is the amount of pistachios and it makes up  of the batch which means that there are six  but cashews always make up  so you get  which is equivalent to two so that leaves two  which you add and that makes  which is equivalent to  or 

Your

There is  pistachios

There is  of almonds

There is 2 cups of cashews

--------------------------

Second problem for pencils 

There is a total of 36 pencils

20 are sharpened

So that leaves 20:16

divide each side by 4

That leaves 5:4
