Here is you're answer:

One of the most simple rules when solving fractions is to "find the common denominator."

Example:

  • \frac{1}{2} + \frac{1}{2} =
  • Find the common denominator:
  • Common denominator is 2:
  • 1 +1=2
  • = \frac{2}{2} = 2

So, in order to solve fractions you first have to find the common denominator of each fraction, then you have to add or subtract the numerators to equal you're answer.

Hope this helps!

Find the difference between (-11,-11) and (-12,-8) round answer to the nearest hundredth
lisov135 [29]

Answer:

Step-by-step explanation:

The two points can be made into a right triangle with the two sides defined by   two lines drawn from the two given points.  Use the Pythagorean Theorem to solve for the hypotenuse, the distance between the two points.  See attached graph.

6^2 + 2^2 = x^2

36 + 4 = x^2

x^2 = 40

x = 6.32
