Relating Fractions, Decimals, and Percents
Percents are ratios that compare a number to 100. Ratio 30 3 = 100 10 50 1 = 100 2 3 75 = 4 100 Decimal Percent 0.30 30% 0.50 50% 0.75 75%
Reading Math Think of the % symbol as meaning per 100 or /100. 75% = 75/100 = 0.75
To convert a fraction to a decimal, divide the numerator by the denominator. 1 = 1 ÷ 8 = 0.125 8 To convert a decimal to a percent, multiply by 100 and insert the percent symbol. 0.125 100 12.5%

Welcome to Pre-Algebra Tuesday! 1. Please have your homework on your desk and complete the warm up. 2. Correct the Facing Math with a red pen – Lesson 16 3. Please get out your journals – 4.3 Making Copies 4. Tonight’s Assignment – Finish Follow-up 4.3
When you use a copy machine to enlarge or reduce a document, you are dealing with similarity. On most copy machines, you indicate how much you want to enlarge or reduce something by entering a percent.
Raphael wants to make posters for his sale by enlarging his 8 ½" by 11" ad. Raphael thinks big posters will get more attention, so he wants to enlarge his ad as much as possible. The copy machines at the copy shop have cartridges for three paper sizes: 8 ½" by 11", 11" by 14", and 11" by 17". The machines allow users to enlarge or reduce documents by specifying a percent between 50% and 200%. For example, to enlarge a document by a scale factor of 1.5, a user would enter 150%. This tells the machine to enlarge the document to 150% of its current size. A. Can Raphael make a poster that is similar to his original ad on any of the three paper sizes-without having to trim off part of the paper? Why or why not? B. If you were Raphael, what paper size would you use to make a larger, similar poster on the copy machine? What scale factor-expressed as a percent- would you enter into the machine?

We use maps to help us find our way in unfamiliar places, to plan vacations, and to learn about other parts of the world. Maps are like scale drawings: they show a large area of land at a reduced size. To get a sense of the size of the place a map represents, you must know to what scale the map was drawn.
