- The third proportional to 1 and 2 is
Solution: The third proportional to two given numbers is the number which is in the same ratio as the other two numbers. This number is found by solving a particular equation.
Definition: The third proportional to two given numbers is a number which is in the same ratio as the other two numbers.
Formula: The formula for finding the third proportional to two given numbers a and b is given by:
a:b = c:x
where x is the third proportional to a and b.
In this question, the two given numbers are 1 and 2.
Therefore, the equation becomes:
1:2 = c:x
Here, c is a constant and x is the third proportional to 1 and 2.
Solving the equation, we get:
1x = 2c
x = 2c
Since c is a constant,
x = 2
Therefore, the third proportional to 1 and 2 is 4.
Hence, the correct answer is Option D. 4.
