We have a question: If a basket is capable of holding 40 fruit altogether, and there are 3 times as many apples as oranges, how many oranges are there?
And an answer: 10
So how you got the answer?
Since the ratio of apples to oranges is 3:1, that means for every 3 apples there is 1 orange. The size of this group is therefore 3 + 1 = 4. We then divide this group size into the total amount of fruit the basket is holding at this time, which is 40. This means there are 40 / 4 = 10 of these groups in total. Since there are 10 of these groups in total, that means there are 10 * 1 = 10 oranges in the basket.

We have a question: Jack has a stack of books that is 12 inches thick. He knows from experience that 80 pages is one inch thick. If he has 6 books, how many pages is each one on average?
And an answer: 160
So how you got the answer?
There are 960 pages because 80 x 12 = 960. Each book is 160 pages because 960 / 6 = 160.

We have a question: There are 60 pieces of chips in Lara's bag. One-sixth of the chips are blue. There are 34 red chips and the rest are green. How many green chips are in Lara's bag?
And an answer: 16
So how you got the answer?
There are 60 x 1 / 6 = 10 blue chips. There are 10 + 34 = 44 chips that are not green. Thus, 60 - 44 = 16 chips are green.
