- If the numerator of a fraction is increased by 250 % and the denominator is increased by 400 % the resultant fraction is 7/19.
Question 1:
If the numerator of a fraction is increased by 250 % and the denominator is increased by 400 % the resultant fraction is 7/19.What is the original fraction?
A. 10/19
Feedback Let the original fraction be x/y, then
350% of x / 500% of y = 7/19
=> 3.5/5 × x/y = 7/19
=> 350/500 × x/y = 7/19
=>7/10 × x/y = 7/19
=> x/y =(7/19 × 10/7) = 10/19
Therefore Original Fraction = 10/19
350% of x / 500% of y = 7/19
=> 3.5/5 × x/y = 7/19
=> 350/500 × x/y = 7/19
=>7/10 × x/y = 7/19
=> x/y =(7/19 × 10/7) = 10/19
Therefore Original Fraction = 10/19
B. 5/9
C. 9/5
D. 19/7
