In this video we learn how to add or subtract fractions with different denominators. We add or subtract (simplify) 7/12+5/18. The steps we follow to add or subtract fractions with different denominators are: 1) Find the LCD. 2) Convert each fraction to an equivalent form with the LCD as the denominator. 3) Add or subtract the fractions. 4) Write the result in simplified form. #addfractions #subtractfractions #simplifyfractions #minutemath #algebrahelp #prealgebra #beginningalgebra #mathhelp #onlinemathvideos #math #mathvideos #oer #openeducation #freemathvideos Here is the link to our website which covers this topic more in depth: https://minutemath.com/pre-algebra/add-and-subtract-fractions-with-different-denominators/ Every Month we have a new GIVEAWAY that is FREE to Enter.
