Final answer:
To add an amendment to the Constitution in the United States, three-fourths (3/4) of the states need to vote in favor. This means that 38 states are needed based on a total of 50 states.
Step-by-step explanation:
The question is about determining how many states are needed for an amendment to be added to the Constitution, based on the requirement that three-fourths (3/4) of the states need to vote in favor.
To find the number of states needed, we first need to calculate three-fourths of the total number of states. Three-fourths can be written as a decimal by dividing 3 by 4, which is 0.75.
Then, we multiply the decimal by the total number of states (50) to get the result. In this case, 0.75 multiplied by 50 equals 37.5. Since we need to round up to the nearest whole number, we round 37.5 up to 38. Therefore, 38 states are needed for an amendment to be added to the Constitution.
