### Proportions powerpoint

1. 1. Proportions by Ms. Johnson
2. 2. Marshall bought 8 potatoes for \$1.60. How many potatoes could he buy for \$3.00? <ul><li> Step 1: Label the proportion with the items you are comparing, and fill in the numbers. </li></ul> Step 2: Multiply the diagonals.  Step 3: Solve by isolating the x. x 8 * 3.00 = 1.60x 24 = 1.6x 15 = x /1.6 /1.6 Potatoes Dollars 8 1.60 3.00
3. 3. What is 40% of 20? <ul><li> Step 1: Write the percent over 100. Write the number by “is” in the numerator, and the number by “of” in the denominator. </li></ul> Step 2: Multiply the diagonals.  Step 3: Solve by isolating the x. x 40 * 20 = 100x 800 = 100x 8 = x /100 /100 40 100 20
4. 4. Unit Reflection <ul><li>I liked the proportions word problems that related to shopping. </li></ul><ul><li>I didn’t like the problems that involved decimals. </li></ul><ul><li>The hardest part was solving percent problems when I didn’t see an “is” or “of” in the problem. </li></ul><ul><li>The easiest part was solving the proportions after I wrote them. I learned how to do that in elementary school. </li></ul>
