Fractions Decimals Percents

We added to our wall of fractions and decimals today. We now can slot percentages into the mix.

We took some time to verify the order of all of the cards, and showed some equivalences written in other forms. We noticed some challenges with small percents for example 0.2% is 0.2/100 which is 2/1000 or 1/500. In decimal form it is 0.002 (we divide percents by 100 to write them as decimals.

We also learned that fractions with denominator of 9 have a neat property. 4/9=0.44444444, 5/9=0.5555555 7/9=0.7777777

We looked at some financial implications (calculating sales tax, or looking at inflation percentages, and looking at percentage appreciation ans depreciation).

impressive collaboration today to get all these cards sorted out!
