Agenda Objective *Fraction & Decimal Investigation *Conversion Formula
*Matching Activity CCSS.MATH. CONTENT. 8.NS.A.1 I can change every repeating decimal into a rational number.
7
Vocabulary Terminating Decimal - a decimal number that ends
Repeating decimal -a decimal number that repeats one or multiple digits infinitely Vinculum - the bar that shows a repeated digit after the decimal point
8
Take 3 minutes and write the decimal
equivalent for as many fractions as you can WITHOUT a calculator.
9
Now use the calculator to complete the chart. Write repeating decimals
with the bar notation (called the vinculum). *What operation does the fraction bar indicate? How can we simply? 𝟒 𝟏𝟓 = ? ÷?
10
Discuss your results with your team.
Can you spot any patterns with repeating decimals?
11
Which denominators yield a Terminating decimal? Repeating
12
What about 7?
13
When the denominator is 7, the same six digits repeat.
14
What about denominator of 99?
Investigate denominators greater than 9-can you find any others that result in repeating decimals? What about denominator of 99? Primes? multiples of 3?
15
IF DEMONINATOR IS 9, DIGIT REPEATS 99, TWO DIGITS REPEAT..
THE RULE OF 9’S IF DEMONINATOR IS 9, DIGIT REPEATS 99, TWO DIGITS REPEAT.. 41 99 32 99
