Percent to Decimals Day 1 Bell Work Write each ratio as a part to part, part to whole, and a whole to part. 1. 18 out of 24 students take a music class in middle school. 2. Out of 12 cats, three have stripes. 3. 7 out of 8 flowers are pink. 4. Kristen sold 475 out of 500 boxes of Girl Scout cookies. 5. 6 out of 30 students get an A in Mrs. E’s class. Justify your Response Vocabulary • Proportion - an equation that shows two ratios are equivalent. • Fraction - a number that represents part of a whole or part of a set. • Decimal- a representation of a real number using the base ten and decimal notation, such as 201.4, 3.89, or 0.0006. • Percent - a ratio that compares a number to 100. • Rational Number - a number that can be written as a fraction • Number Line - a line on which numbers are marked at intervals, used to illustrate simple numerical operations. I Can…. Convert measurements using proportional reasoning. 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? 1. 4. = 12 . ?

I Can…. Convert decimals to fractions. Convert Decimals to Fractions Essential Understanding: To convert a decimal to a fraction you simply identify the place value of the last decimal place and use it as the denominator of the fraction. Simplify when possible. Examples: .1 .25 .375 .4213 Your Turn…. • Clear your desk of everything but a pencil and a calculator.

I Can…. Convert decimals to percent. Converting Decimals to Percent. Essential Understanding: • To convert a decimal to a percent, you simply multiply the decimal by 100 and add ass a percent sign (%). • The easiest way to do this, is to use your knowledge of Powers of 10 (move the decimal to the right two places) Examples: .25 = .1 = .375 = 1 2 = = Practice Please take out your maker boards Wrap it Up • Review • Questions • Exit Tickets Day 5 Bell Work Convert each decimal to a percent. .05 = .1 = .25 = .01 = 2.25= .82 = .12 = .064 = .333 = .6 = .9 = .0001 = Homework Check Vocabulary - an equation that’s shows two ratios are equivalent. • Proportion _________ - a number that represents part of a whole or part of a set. • Fraction _______ • Decimal______ a representation of a real number using the base ten and decimal notation, such as 201.4, 3.89, or 0.0006. - a ratio that compares a number to 100. • Percent _______ Number - a number that can be written as a fraction • Rational _____________ Line - a line on which numbers are marked at intervals, • Number ___________ used to illustrate simple numerical operations.
