Question

The sum of two rational numbers is 45 one of the number is twice the other what
are the numbers ?​

Answer 1

Answer:

15,30

Step-by-step explanation:

let the one number be x

then other number = 2x

according to question,

x+2x = 45

3x = 45

= x = 45/3 = 15

therefore the numbers are-

first number= x = 15

second number = 2x = 2×15 = 30

so the rational numbers are 15 and 45

Answer 2

Question:

The sum of two rational numbers is 45.One of the number is twice the other .What are the numbers?

Answer:

☞︎︎︎Let the numbers be "x" and "y"

A/Q

x+y=45

=> x = 45-y -------①

Also,

x=2y-------②

☞︎︎︎Comparing the value of "x" from ① and ②, we get,

2y = 45 - y

=> 2y + y = 45

=> 3y = 45

=> y = 15

☞︎︎︎Putting value of "y" in equation ②

x = 2y

=> x = 2 × 15

=> x = 30

The numbers are 30 and 15
