Fractional Coefficients Objective: To solve equations and inequalities involving fractional coefficients.
To solve an equation or an inequality having fractional coefficients it is helpful to multiply the equation by the LCD Example: solve for x Multiply the equation by the LCD
Joe can finish the class project in 10 hours and Sam can finish the same job in 8 hours. If Joe starts at 1pm and Sam helps him 2 hours later will he have time to watch his TV show at 8 pm? Joe can finish 1/10 th of the job per hour Sam can finish 1/8 th of the job per hour but starts 2 hours later
Joes work plus Sams work has to equal to 1(the whole job) Joe and Sam must finish the job in less than 7 hours. Since h is less than seven yes, he can watch his show.
