There are two numbersare 7:5. Their sum is 12. What is the difference between the two numbers

7 - 5 = ?

7-5=2

the H.C.F and L.C.M of two number are 8 & 504 respectively. one of the numbers is 72 find the other number

To find the difference between the two numbers, we first need to determine the values of the two numbers based on the given information.

Let's assume the two numbers are represented by variables x and y.

According to the given ratio, the two numbers are in a ratio of 7:5. This means that the first number (x) is 7 times the value of the second number (y).

We can set up an equation using this information: x = 7y.

The sum of the two numbers is given as 12. Therefore, we can also set up another equation: x + y = 12.

Now we can solve these two equations simultaneously to find the values of x and y.

Substituting the value of x from the first equation into the second equation, we get: 7y + y = 12.

Combining like terms, we simplify: 8y = 12.

Dividing both sides of the equation by 8, we find: y = 1.5.

Now that we know the value of y, we can substitute it back into the first equation to find x: x = 7 * 1.5 = 10.5.

Therefore, the two numbers are 10.5 and 1.5.

To find the difference between these two numbers, we subtract the smaller number from the larger number: 10.5 - 1.5 = 9.

So, the difference between the two numbers is 9.
