Pls answer fast

Answer 1

Step-by-step explanation:

Ratio of the two numbers=7:10

Let the two numbers be 7x and 10x, since these two numbers are also in the ratio 7:10.

It is given that their difference is 105.

This implies that either 7x-10x=105 or 10x-7x=105.

First let's take 7x-10x=105.

=> -3x=105

Dividing both sides by -3,

x= -35

This implies that 7x= 7 * (-35)= -245

10x= 10 * (-35)= -350.

If we take the second equation,

10x-7x=105,

3x=105

x=35

This implies that the numbers are 7x=245, 10x=350.

Therefore, the numbers are either -245,-350 or 245,350.
