  3. Day 1

  4. Bell Work Write each ratio as a part to part, part to whole, and a whole to part. • 18 out of 24 students take a music class in middle school. • Out of 12 cats, three have stripes. • 7 out of 8 flowers are pink. • Kristen sold 475 out of 500 boxes of Girl Scout cookies. • 6 out of 30 students get an A in Mrs. E’s class. Justify your Response

  5. Vocabulary • an equation that shows two ratios are equivalent. Proportion - • a number that represents part of a whole or part of a set. Fraction - a representation of a real number using the base ten and decimal notation, such as 201.4, 3.89, or 0.0006. Decimal- Percent - a ratio that compares a number to 100. a number that can be written as a fraction Rational Number - a line on which numbers are marked at intervals, used to illustrate simple numerical operations. Number Line -

  6. I Can…. Convert measurements using proportional reasoning.

  7. Converting Measurements Essential Understanding: To convert measurements from one unit to another, you can use your knowledge of ratios to create a poprpotion. Example: Mrs. E’s desk is 4 ft. long. How many inches is it?

  31. Converting Decimals to Percent. Essential Understanding: • To convert a decimal to a percent, you simply multiply the decimal by 100 and ass a percent sign (%). • The easiest way to do this, is to use you knowledge of Powers of 10 (move the decimal to the right two places) Examples: .25 = .1 = .375 = = = add r
