Page 135-136 Odds

1. Jordan is right. To convert a decimal to a percent you must multipy by 100.
0.003 x 100= 0.3
0.3%

3. Both Mark and Jonas are correct. The simplest answer is that Mark and Jonas' team scored 5 while their opponent scored 1.


Notice that there is 500/100 which is 500% like Mark said and that you multiply the denominator by 5 to get the numerator like Jonas said.

5. The answer will be in picture form and simplified.



I know the picture is screwed up. I'm sorry.

7. Here is the next one.


9. Last but not least question 9.


Here is a quick but good video to understand converting decimals, fractions and percents.


I know that my post was flawed because of Paint and Word. If you have suggestions or comments please post.
PS. My post was late because I could not get on the blog all weekend.

Jocelle Garcia's scribe post


a) Maria walked 420m.

b) Walter walked 323m.

c) Maria, because she walked 97m further than Walter.




a² = c² - b²
a² = 80cm² - 79cm²
a² = ( 80 x 80 ) - ( 79 x 79 )
a² = 6,400cm² - 6,241cm²
a² = 159cm²
√a² = √159cm²
