How do you combine like terms with fractions with different denominators?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

How do I combine like terms in math?

A common technique for simplifying algebraic expressions. When combining like terms, such as 2x and 3x, we add their coefficients. For example, 2x + 3x = (2+3)x = 5x.

How do you combine like terms and simplify?

Like Terms: Terms that have identical variable parts (same variable(s) and same exponent(s)). When simplifying using addition and subtraction, you combine “like terms” by keeping the “like term” and adding or subtracting the numerical coefficients.

How do you combine like terms?

Terms are separated by “++” and “ – – “signs.

  • Like terms are terms with the same variables and same powers.
  • Be sure to use the “++” or “ – – “that is in front of the coefficient.
  • What is collecting like terms?

    Collecting like terms means to simplify terms in expressions in which the variables are the same. In the expression , the terms and are like terms, as are and .

    What is combining like terms in Algebra?

    A frequently-used procedure in algebra is the process of combining like terms. This is a way to “clean-up” an equation and make it much easier to solve. In case you’ve forgotten, a term is each single part of an expression. For example, in the expression 4x + 3 + 7y, there are three terms: 4x, 3, and 7y.

    What does combine like terms mean?

    Like terms are the parts of an expression that have the same algebraic variable (same letter).

  • Collecting like terms means to count up how many of each different letter there are in an algebraic expression.
  • We combine like terms to make an expression shorter and simpler.
  • To collect like terms,add up the numbers in front of each letter separately.
