For this project, students in Mrs. Beile's learning center math class were tasked with creating a Powerpoint presentation that explained how to solve a math problem. The students were expected to select a math concept they were struggling with themselves and pretend they were explaining the concept to a friend. By going through the process, the students were able to develop mastery and reinforce the concept for themselves. Everyone did a fantastic job!

### Subtracting Mixed Fractions by Chris Wilson

1. 1. Subtracting Mixed Fractions By Chris Wilson
2. 2. Solve:4 3/10 – 2 2/8 <ul><li>Solution: Subtract the fractions using common denominators. Then subtract the whole numbers. </li></ul>
3. 3. Step 1. <ul><li>List the LCM of both mixed numbers. </li></ul><ul><li>10 : 10, 20, 30, 40 , 50 </li></ul><ul><li>8 : 8, 16, 24, 32, 40 </li></ul><ul><li>The LCM is 40 </li></ul>
4. 4. Step 2. <ul><li>Take the fraction part of the whole numbers and multiply them until the denominator is 40. </li></ul><ul><li>3/10 x 4/4 = 12/40 2/8 x 5/5 = 10/40 </li></ul>
5. 5. Step 3. <ul><li>Now subtract the whole numbers </li></ul><ul><li>4-2=2 </li></ul>
6. 6. Step 4. <ul><li>After that, subtract the fractions. </li></ul><ul><li>12/40 – 10/40 = 2/40 </li></ul>
7. 7. Step 5. <ul><li>Then reduce the difference of the two fractions. </li></ul><ul><li>2/40 : 2/2=1/20 </li></ul>
8. 8. Step 6. <ul><li>Finally put the difference of the whole numbers and the difference of the fractions together. </li></ul><ul><li>2+ 1/20 = 2 1/20 </li></ul>
