3. 4 Day 1 Solving Fractional Equations
You will have an equation to 1. Solve 2. Find out something about. It is much more likely that you will “solve”
1. Find the x intercept of the graph What does that mean exactly? What should you do to make this problem easy?
Solve the following
Practice problems (cont)
Day 2 Word Problems The idea is to set up a fractional equation based on the criteria of the world problems, then solve. It might be a work problem, a fraction problem, or a mixture problem.
1. 2. 3. 4. 5. 6. The denominator of a fraction is 1 less than twice the numerator. If 7 is added to both numerator and denominator, the resulting fraction has a value of 7/10. Find the original fraction. Jan can tile a floor in 14 hours. Together, Jan and her helper can tile the same floor in 9 hours. How long would it take Bill to do the job alone? How much of a 45% salt solution must be added to a 20% salt solution to get 750 ml of a 30% salt solution? The ratio of 4 less than a number to 26 more than the number is 1 to 3. What is the number? Pipe A can fill a tank in 4 hours and pipe B can fill the tank in 3 hours. With the tank empty pipe A is turned on, and one hour later, pipe B is turned on. How long will pipe B run before the tank is full Chris can jog to Kevin’s house in 10 minutes. Kevin can ride his bike to Chris’ house in 6 minutes. If they start from their own houses at the same time, in how many minutes do they meet? .
