The numerator of a fraction is less than its denominator is increased by 9 and the numerator by 2,the fraction bcms two-third.find d fractn.
Ans is 26/33
To solve this problem, we need to set up a mathematical equation based on the given information.
Let's start by assuming the fraction is x/y, where x is the numerator and y is the denominator.
According to the problem, "The numerator of a fraction is less than its denominator is increased by 9, and the numerator by 2, the fraction becomes two-thirds."
This can be translated into the equation:
((x + 9)/(y + 2)) = 2/3
Now, let's solve this equation step by step:
1. Cross-multiply to eliminate the denominators:
3(x + 9) = 2(y + 2)
2. Distribute the multiplication:
3x + 27 = 2y + 4
3. Simplify the equation:
3x - 2y = -23
The equation above represents the relationship between the numerator (x) and denominator (y) based on the given conditions.
To find the fraction (x/y), we can solve this equation for x and y.
4. Rearrange the equation in terms of x:
3x = 2y - 23
5. Divide by 3:
x = (2y - 23)/3
Now, let's find the possible values of x and y that satisfy the equation.
6. Substitute this value of x in the original equation:
((2y - 23)/3 + 9)/(y + 2) = 2/3
7. Cross-multiply:
3(2y - 23 + 9) = 2(y + 2)
8. Distribute the multiplication:
6y - 69 + 27 = 2y + 4
9. Simplify the equation:
6y - 42 = 2y + 4
10. Move the terms, involving y, to one side of the equation:
4y = 46
11. Divide by 4:
y = 11.5
Now we have found the value of y, which is 11.5.
12. Substituting y = 11.5 back into the equation x = (2y - 23)/3:
x = (2(11.5) - 23)/3
x = (23 - 23)/3
x = 0/3
x = 0
Therefore, the numerator (x) is 0 and the denominator (y) is 11.5.
But since fractions are usually written with whole numbers as numerator and denominator, we can multiply both the numerator and denominator by a number to make them both whole numbers.
13. Multiply the numerator and denominator by 2 to get whole numbers:
x' = 0 * 2 = 0
y' = 11.5 * 2 = 23
The fraction in its simplest form is 0/23.
