Question

Find two numbers if their sum is 6.1 and their difference is 1.6? what are the 2 numbers?

Answer 1

This is a sum and difference problem,
larger number = (sum+difference)/2 = (6.1+1.6)/2 = 3.85
smaller number = (sum - difference)/2 = (6.1-1.6)/2 = 2.25

Answer 2

Answer:

3.85 and 2.25.

Step-by-step explanation:

Let x and y represent two numbers.

We have been given that sum of two number is 6.1. We can represent this information in an equation as:

$x+y=6.1...(1)$

We are also told that there difference is 1.6. We can represent this information in an equation as:

$x-y=1.6...(2)$

Upon adding both equations, we will get:

$x+x+y-y=6.1+1.6$

$2x=7.7$

$\frac{2x}{2}=\frac{7.7}{2}$

$x=3.85$

Upon substituting $x=3.85$ in equation (1), we will get:

$3.85+y=6.1$

$3.85-3.85+y=6.1-3.85$

$y=2.25$

Therefore, our required two numbers are 3.85 and 2.25.
