Question

the numerator of the rational number - 7/3 is ​

Answer 1

Answer:

FIRST Find the LCM of the denominators of the numbers { 3/5 and 7/6}. so it will be 30. [ here denominators are 5 and 6.]

Multiply and divide the first number {3/5} by 6 =18/30

Multiply and divide the second number {7/6} by 5= 35/30

Now, take the numerator between 18 to 35.

Answers are: 19/30, 21/30, 34/30, etc

Answer 2

Answer:

Let the numerator of the rational number be x.

Then, the denominator of the rational number =x+3

According to the given condition,

New numerator =3x and new denominator =(x+3)+20=x+23

Given,

x+23

3x

=

8

1

By cross multiplying, we get

8(3x)=x+23

⇒24x=x+23

⇒23x=23 ....[On Transposing]

or x=1

Therefore, numerator of the rational number =1 and denominator =1+3=4.

Hence, the original rational number is

4
