Today we did Number of the day 7839.126 and it's Homework !.






Then we use the MATHLINKS 7 ,to Probability. page 162. 1- 12.













like these questions:













If there are Six planes all for the air show. What if the blue land or






the purple land.
a. P(Blue and Purple )




b.P( silver and Orange)






` Fraction 1-4
Ratio


the ratio of A:B is 2:5




Decimal 0.25




Percent 125%





The question was if the blue would land and the purple would land, they will be six planes


in the air show.





so that means 2 planes will land and 4 other planes will still be in the air so the fraction, the decimal , the percent and the ratio will be.....





Fraction 2-6 or 1-3





Ratio 1:3 or 2:6





Decimal 0.3333









Percent 3.33%




so the other questions were..... Ben`s activities
so the answer of Ben`s actvities was





3-5 : fraction





3:5: ratio





0.6 : decimal





60 % : percent

I choose Damien b for the next scribe post
