ANSWER is 25% of what number ANSWER 40% 4.What percent of 90 is 36? ANSWER d = 4 ANSWER x = Solve:

Solve Equations With Fractional Coefficients Goal: Solve equations with fractional coefficients

Coefficient The number being multiplied by the variable. Ex: 2x is the coefficient

Proportion v.s. Fractional Coeff

Find the LCD

3 Steps For Solving Fractional Coefficients Step 1: Use the LCD of all fractions on both sides of the equation. Then change the denominators. LCD= 12

3 Steps For Solving Fractional Coefficients Step 2: Combine the like Terms.

Step 3: Multiply both sides by the LCD. LCD= 12

Examples 9 = x Step 1: Use the LCD of all fractions on both sides of the equation Step 2: Combine the like Terms. Step 3: Multiply both sides by the LCD. LCD = 12x
