Question

if the numerator is greater than the denominator both increase by 1 the ratio between 1:2. if both decreased by 1 the ratio becomes 1:4, find the ratio

Answer 1

Answer:

Step-by-step explanation:

Let numerator be x and denominator y

Fraction - x/y

Case -1

x + 1/ y + 1 = 1/2

2x + 2 = 1 + y

y = 2x + 1 -- Eq.1

Case - 2:

x - 1/ y -1 = 1/4

4x - 4 = y - 1

4x - 4 = 2x + 1 - 1 ( Value of eq.1)

2x = 4

x = 1/2

If x is 1/2:

y = 1 + 1 = 2

Hence 1/2 divided by 2 = 1/4
