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 \(\frac{1}{6}\)

almonds make up \(\frac{1}{3}\)

cashews make up \(\frac{1}{2}\)

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 \(\frac{3}{6} or \frac{1}{2}\) left so the answer is 3 cashews

Answer=3 cups of cashews 

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

Batch 2:


1 cup of cashews which makes up \(\frac{1}{2}\)or \(\frac{3}{6}\) of the batch and there are \(\frac{2}{3}\) of a cup of almonds so that leaves only \(\frac{1}{3} or \frac{2}{6}\) as the only option left

Answer= \(\frac{2}{6}\) of pistachios

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

Batch 3:

\(\frac{4}{6}\) is the amount of pistachios and it makes up \(\frac{1}{6}\) of the batch which means that there are six \(\frac{4}{6}\) but cashews always make up \(\frac{1}{2}\) so you get \(\frac{12}{6}\) which is equivalent to two so that leaves two \(\frac{4}{6}\) which you add and that makes \(\frac{8}{6}\) which is equivalent to \(1 \frac{2}{6}\) or \(1 \frac{1}{3}\)

Your answer:

There is \(\frac{4}{6}\) pistachios

There is \(1 \frac{1}{3}\) 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
