Explanation
- The fraction of 4/7 must be added to itself to get the given sum.
Let say required fraction is y/z and according to the given condition; 4y/7z + 4/7 = 15/14
After solving this equation; y/z = 7/8 which is our required answer.
To Find
Fraction of 4/7 = ?
Solution
Let suppose the fraction = y/z
Now;
4y/7z + 4/7 = 15/14
4/7 (y/z + 1) = 15/14
y/z + 1 = (15 x 7)/(14 x 4)
y/z + 1 = 15/8
y/z = 15/8 – 1
y/z = (15 – 8)/8
y/z = 7/8 answer
Conclusion
7/8 fraction of 4/7 must be added to itself to make the sum 15/14.
