Let us use proportion:
a:b = c:d
where: 
ad = bc

A) 3:8 = 2:6 ⇒ 3*6 = 8*2 ⇒ 18 = 19 NOT

B) 3:6 = 2:9 ⇒ 3*9 = 6*2 ⇒ 27 = 12 NOT

C) 3:8 = 2:5 ⇒ 3*5 = 8*2 ⇒ 15 = 16 NOT

D) 3:9 = 2:6 ⇒ 3*6 = 9*2 ⇒ 18 = 18 YES!!!

Adams puts 3/4 of a bag of pens in 3 boxes. If he opens the boxes one by one, how many pens will be in each box

Answers

The number of pens in each bag if Adams puts 3/4 of a bag of pens in 3 boxes is (1)/(4) of a bag.

Given that:

Adams puts a fraction of (3)/(4) of a bag of pens in 3 boxes.

It is required to find the number of pens in each box.

Total number of a fraction of pens available = (3)/(4) of a bag

These pens are equally distributed among 3 boxes.

So, each box will have an equal number of pens.

So, the number of pens in each box is:

n=(3)/(4) /3

Take the reciprocal of the second number and the operation becomes multiplication.

n=(3)/(4) *(1)/(3)

  =(1)/(4)

Hence, the number of pens in each box is (1)/(4) of a bag.
