What are the steps to adding and subtracting unlike denominators?

- Change the fractions, so the denominators are the same. The easiest way to do this is to multiply both the numerator and denominator of each fraction by the denonimator of the other.
- Add or subtract the numerators and put the result over the new denominator you calculated in step 1.
EXAMPLE:
1/2 + 1/3 = (1/2)3 + (1/3)2 = (1 x 3)/(2 x 3) + (1 x 2)/(3 x 2) = 3/6 + 2/6 = 5/6
1/2 - 1/3 = (1/2)3 - (1/3)2 = (1 x 3)/(2 x 3) - (1 x 2)/(3 x 2) = 3/6 - 2/6 = 1/6

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.
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 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.
How do you use MDAS in math?
MULTIPLY AND DIVIDE 1ST..THEN AFTER PERFORMING THIS STEPS YOU CAN NOW PROCEED WITH ADDING OR SUBTRACTING THE GIVEN NUMBERS NOTE: MULTYPLY AND DIVIDE IS EQUAL..... ADDITION AND SUBTRACTION IS ALSO EQUAL Example: = 9*5-100/5 =(45)-(20)
What are the steps of subtracting dissimilar fractions?
Example 7/9 - 2/5 1. Make denominators the same (they're the bottom bits) 7/9*5/5 = 35/45 2/5*9/9 = 18/45 2. Now they're the same 35/45 - 18/45 = 17/45

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 in subtracting dissimilar fractions?
Step I: Find the LCM of the denominators. Step II: Find equivalent fraction such that the new denominators are the LCM. Step III: Carry out the subtraction on these numerators to arrive at the new numerator. Step IV: New denominator = LCM. Step V: Simplify the fraction.
