Answer:
The fractional change is % .
Step-by-step explanation:
Given as :
The original fraction =
Where numerator = x
Denominator = y
According to question
The numerator decreased by 50%
Let The new numerator = x' = x - 50% of x
I,e x' = x ( 1 - )
Or, x' = x ()
Or, x' = x
or, x' = .........A
Again
The new denominator = y' = y - 25% of y
i.e y' = y (1 - )
Or, y' = y ()
Or, y' = y ()
Or, y' = ............B
So, The new fraction = =
Or, =
So, The fractional change = × 100
Or, The fractional change = × 100
Hence, The fractional change is % . Answer
