x - 10 = x/10
10x - 100 = x
9x = 100
x = 100/9
x = 11.1111...
You do the following: 1) Divide the second number by the first. This will give you a factor, for example 1.20. 2) Subtract 1 from the result. This gives you the increase as a factor, for example, 0.20. 3) Multiply the result by 100, to convert to a percentage. In this example, 20%.
Whatever is required by the context of the question. Whether or not the number is negative gives no indication as to whether to add or subtract.

7 subtracted from the quotient of a number and 2 is a -6
If the number is x then: x+4-9 = -2 and so x = 3
Six-and-a-quarter
Subtract 32, then divide the result by 1.8 which gives the result 48.889 to three decimal places.
Roughly 25.5 percent. To get the answer, divide the smaller number by the larger number, which will give you .745. You then subtract that from 1, which gives you the answer. Or, subtract 74.5 from 100, which will give you the same answer.

Unless your calculator has a key for it, the only method I know is awkward. Example : Take 24 and 114. Divide 114 ÷ 24. It gives 4.75. Subtract the integer part (4) to keep only the fraction part (0.75). Remultiply by 24. This gives 18. Do the same thing with the smallest number 24, and the new number 18. Divide 24 ÷ 18. It gives 1.33333333. Subtract the integer part (1) to keep only the fraction part (0.3333333). Remultiply by 18. This gives 12. Do the same thing with the smallest number 18, and the new number 12. Divide 18 ÷ 12. It gives 1.5. Subtract the integer part (1) to keep only the fraction part (0.5). Remultiply by 12. This gives 6. Do the same thing with the smallest number 12, and the new number 6. Divide 12 ÷ 6. It gives 2.0. When there is no fraction part left, the game is over, and the smallest number found is the GCF. So the answer is 6. Another example with 17 and 35. Divide 35 ÷ 17. It gives 2.05882352941. Subtract the integer part (2) to keep only the fraction part (0.05882352941). Remultiply by 17. This gives 1. Start again with the smallest number 17, and the new number 1. Divide 17 ÷ 1. It gives 17.0. There is no fraction part left, so the answer is the smallest number found, which is 1. When two numbers have no common factors, the answer will always be 1, since you can divide anything by 1.
To find the number, we can divide 24 by 0.12. The result is 200, so the number that when multiplied by 0.12 gives the product 24 is 200.
Divide any number by pi (which gives its result in units of pi) or use rad, which converts standard measures into angles of pi.
Subtract the difference from 10 and divide by 2. This gives the lower number. Now add 1.4 to that and you get the higher number. If you find that beyond you try 4.3 and 5.7
Calculating the average of the two numbers gives you the answer. (Add the two numbers, then divide the result by 2.)
The answer is 24.
You first subtract two velocities at two different time intervals. This gives you a difference of velocity. Then you divide this by the time.
You may subtract a positive number from a negative number by simply just adding the two numbers, disregarding their signs, and giving the sum a negative sign. For example, if we have to subtract 3 from -5, then you just add 3 and 5 which gives you 8. The final answer must be -8.
