Subtracting Expressions with Rational Coefficients
Subtracting Expressions with Rational Coefficients is a Grade 7 math skill from enVision, Mathematics, Grade 7, covering Generate Equivalent Expressions. To subtract expressions with rational coefficients, apply the same properties as with integers. Distribute the negative sign to each term in the expression being subtracted, then combine like terms using the rules for adding and subtracting fractions and decimals. Explanation This skill applies the process of subtracting expressions to terms with decimal and fractional coefficients. The fundamental steps of distributing the negative and combining like terms remain exactly the same.
