Question

the denominator of a rational number is 4 more than its numerator . if the numerator is increased by 4 and denominator by 6 the rational number becomes 3/5 . the rational number is

Answer 1

Answer:

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Answer 2

Step-by-step explanation:

Let the numerator of the rational number be x.

Then, the denominator of the rational number =x+4

It is given that the numerator is increased by 2 and the denominator is increased by 3 to get the new rational number

4

3

.

According to the given condition,

(x+4)+3

x+2

=

4

3

By cross multiplying, we get

4(x+2)=3(x+7)

⟹4x+8=3x+21

⟹4x−3x=21−8 ....[Transposing 3x to LHS and 8 to RHS]

or x=13

Therefore, numerator of the rational number =13 and denominator =13+4=17.

Hence the original rational number is

17

13
