In method

Answer 1

1:

Let the ratio of red peppers to green peppers be 3x:4x, where x is a positive integer.

Since the total number of peppers is the sum of the red and green peppers, we have:
3x + 4x = total number of peppers
7x = total number of peppers

Since the total number of peppers is given, we can substitute that in:
7x = total number of peppers

Since the ratio of red peppers to green peppers is 3:4, we can say:
3x = number of red peppers

Therefore, there are 3x red peppers in the truck.
