Example Question #131 : Numbers And Operations
In a barrel there are apples. If there are red apples for every green apples, how many of the apples in the barrel are green?
If there is a group of green apples for every group of red apples, then in every group of apples there will be green ones and red ones. (). How many groups of apples are there in a barrel containing apples? divided by is , so there are groups of apples. In each group of apples, there is a smaller group of green apples, so there are groups of green apples each. , so there are green apples in a barrel of apples.
Alternatively, one could say that since there are green apples in every group of apples, the fraction of green apples in the barrel is . To find of , multiply and together. is , so there are green apples in the barrel.
Example Question #132 : Numbers And Operations
Each of the points on the line above is the same distance from the next. If the distance between point A and point F is inches, what is the distance between point A and point C?
inches
inches
inches
inches
inches
inches
There are five segments of line between points A and F. divided by is , so each line segment is inches long. There are line segments between points A and C. line segments inches each inches, so inches is the correct answer.
Alternatively, since there are line segments between points A and F and line segments between points A and C, line AC is of the total line AF. To find of , multiply and . , so the correct answer is inches.

There is a shipment of computer screens arriving today. If there are 1,400 screens, and 35% of them are 23 inches wide, what is the number of 23 inch-wide screens?
There is a shipment of computer screens arriving today. If there are 1,400 screens, and 35% of them are 23 inches wide, what is the number of 23 inch-wide screens?
We need to find the portion of screens from the whole.
First, we need to convert our percent to a decimal:
Next, multiply the total number by our new-found decimal
So our answer is 490
