Fractions Decimals OH MY!! Percents

Today’s Objective IWBAT convert from fractions to decimals. .4

Parts of the Whole Fractions, Decimals, and Percents all represent parts of the whole This means that you can easily change among the three

Fractions  Decimals To convert from a fraction to a decimal… Set up the fraction like a division problem. Divide!

Fractions  Decimals To convert from a fraction to a decimal… Set up the fraction like a division problem.

Fractions  Decimals Repeating Decimals Some decimals form a pattern that goes on and on forever and ever. If I start seeing the same number over & over again, then I know it will be a repeating decimal. To show that it repeats, I put a line over the number(s) that repeat. Like this:

Fractions  Decimals 6 6 6 Repeating Decimals . 3 2.0 2 18 2 0.666 .6 18 2 18 2

Fractions  Decimals 8 3 3 Repeating Decimals . 6 5.0 5 48 2 0.833 .83 18 2 18 2
