When adding two fractions with unlike denominator's which of these steps is the first step?

The first step is to make the denominators the same.

Are the steps for like and unlike denominators the same or different?

It depends what you are doing with the fractions. If you are multiplying or dividing fraction, the denominators do not need to be the same and the calculation can be carried out immediately. If you are adding or subtracting fractions, the denominators must be the same; if you have different denominators, the fractions must first be changed into equivalent fractions with the same denominator. When the denominators are the same (or have been made the same as equivalent fractions from being different) the calculation can be carried out.

What are the steps to subtracting fractions?

Same as for addition. Mainly, you have to convert the fractions to equivalent fractions that have the same denominator. After that, it is easy: just subtract the numerators and put the result on top of the common denominator.

What are the steps to subtract unlike fractions?

first find a common denominator then subtract the top numbers

What is the trick when adding fractions?

The trick to adding fractions is three simple steps. First, make sure the bottom numbers (the denominators) are the same. Secondly, add the top numbers (the numerators), put the answer over the denominator. Finally, simplify the fraction if need be.

What are the rules for adding and subtracting positive and negative fractions with different denominators?

first must find Least Common Denominator First of all, if you want to know about adding fractions, check out "How to Add Fractions". Be sure to follow the math examples carefully. To subtract fractions, follow the same steps as for adding, except subtract where you would add. Now about those positive and negative signs. The rules are the same whether you are working with integers or fractions. I will give you a method of learning the rules for the signs that has worked for many other students. Copy off this "Rules for Integers" chart and paste it on a large index card. Put the card in your math book or folder and refer to it often while you are doing your homework. If you keep using the card, you will get better with the signs.

When are fractions used in music?

there are fractions in whole steps

Do you have to find a common denomiter in dividing fractions?

NO!!!! When dividing fractions the steps to take are : - #1 ; Convert to Improper Fractions. #2 ; Very Important ; change the sign to multiply and invert(turn over) the right hand fraction. #3 Then proceed as for multiplication. e.g. 2 1/2 divide 3/4 = 5/2 divide 3/4 = 5/2 X 4/3 NOTE what has happened. Cancel down by '2' 5/1 x 2/3 10/3 3 1/3 The answer.

What is the meaning of 2 step equation?

two algebraic steps (not counting simplification steps) must be used to solve the problem. 1st step is adding or subtracting some quantity from both sides of the equation. 2nd step is multiplying or dividing by a number to solve.

What ingredients are in adding fraction?

If you mean the steps, they are as follows:* Identify a common denominator. Any common denominator will do. * Convert both fractions to equivalent fractions, with the common denominator found in the previous step. (If the fractions start off with the same denominator, there is nothing else to do in these first two steps.) * Add the numerators. That's the numerator of the result. Copy the common denominator as the denominator of the result. * Check whether you can simplify the resulting fraction.

How do you make the screen shake in Game Maker?

If you're making a 2D game, you can create this effect by adding or subtracting a small random amount to the main view's x and y coordinates every few steps.
