Question

Give two consecutive whole numbers whose sum is 9. Find consecutive whole numbers?​

Answer 1

Step-by-step explanation:

let the two consecutive numbers be X and X + 1

now according to the question the sum of X and X + 1 is equals to 9

X + X + 1 =9

2x + 1 = 9

2x = 9-1

2x = 8

x = 8/2

x = 4

and X + 1 = 4+1= 5

so that two consecutive numbers are four and five

Answer 2

Answer:

Given:

Sum of two consecutive whole numbers is 9.

To Find:

We need to Find the two consecutive whole numbers.

Solution:

Let the two consecutive numbers be x and x + 1.

Now, according to the question we have,

x + x + 1 = 9

2x + 1 = 9

2x = 9 - 1

2x = 8

x = 8/2

x = 4

Therefore one number is 4 and other is x + 1 = 4 + 1 = 5.
