.6 What fraction of the rectangle is green? They sound alike!!!What decimal part of the rectangle is green? .6
To write a decimal as a fraction, write the fraction as you would say the decimalHundredths Ten-thousandths tenths Hundred-thousandths Thousandths
Say the decimal….Write it as a fractionNotice….when you change a decimal to a fraction the denominator is always 10, 100, 1000 (powers of ten!) 0.5 = 0.65 = 0.22 = 0.2 = 0.225 =
You have to simplify / reduce the fraction if possibleIs that all there is? Of Course Not You have to simplify / reduce the fraction if possible
Write .6 as a fraction .6 = Can be simplified to: BUT .6 = SO
What about fractions to decimals?You can write a fraction as a decimal by dividing the numerator by the denominator…..the fraction symbol means division!
To make a decimal…do the division!.00 28 20 .75
One more thing……… When you divide, REMEMBER, add zeros to finish your division. AND 2 THINGS CAN HAPPEN
The division problem endsA Terminating decimal The division problem goes on forever….Repeating decimal
Repeating Decimals A single digit might repeat…. .3333….Or a group of digits might repeat… ….
Show repeating decimals by placing a line over the digit or group of digits that repeats.33333…. Becomes .3 And ….becomes .275
Remember Will be 1.4 1.2 will be Simplified to:Whole numbers stay the same!
