Final answer:
To find out how many quarters are in 2 halves, it is understood that each half is equivalent to 2 quarters, hence 2 halves would equal 4 quarters.
Step-by-step explanation:
To determine how many quarters are in 2 halves, you would use the concept that each half can be divided into two quarters. Therefore, if you have two halves, you would have a total of four quarters. This is because:
- 1 half = 2 quarters
- 2 halves = 2 quarters + 2 quarters
- 2 halves = 4 quarters in total
This can be visualized using the example of a pie. If you picture a whole pie and cut it into half, each half can be further divided into two pieces to make quarters. If you start with two halves of the pie, you will end up with four quarter pieces after you cut each half into two.
