Question
Solve the proportion
- 1
- 3
- 6
- 5
Hint:
A proportion is an equation in which two ratios are set equal to each other.
The correct answer is: 1
Here, we have to find the missing number.
Let the missing number be x.
Or, 3/12 = x/4
By cross multiplication, we get
Or, 12 × x = 3 × 4
Or, 12x = 12
Or, x = 12/12
Or, x = 1.
Hence, the correct option is (a).
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
