NOV 20 SCRIBE (PEE)

Today in math class, Mr. Harbeck gave us our third quiz. This quiz was based on our knowledge towards fractions.

Quiz 3


What do you know about 5/7?
- numerator is 5 (part)
- denominator is 7 (whole)
- proper fraction
- less than 1

You were then going to convert that fraction (5/7) into a decimal, fraction, percent, and ratio - as shown in the 5 colomns below:


You convert 5/7 to a decimal by dividing 5 by 7. This gives you the answer 0.714. The fraction stays the same. You get the percentage by multiplying the decimal by 100, giving you 71.4%. The ratio is 5:2 because 5 and 2 are the two parts that give you the whole number/denominator, which is 7.

What do you know about 3/2?
- numerator is 3 (part)
- denominator is 2 (whole)
- improper fraction
- greater than 1

The last question was similar to the second question on the quiz. It also asked you to convert the fraction (3/2) to a decimal, fraction, percent, and ratio:


Convert 3/2 to a decimal by dividing 3 by 2 = 1.5. The fraction stays the same. 150% is the answer because you multiply the decimal by 100. There is no ratio because it does not have the two parts. It needs to have a part and a part to make a part of a whole.

Definitions
Fraction - A number that is less than one. The numerator is the part. The denominator is the whole.
Decimal - Represents as part of a whole number using tenths, hundredths, etc.
Percent - An equivalent fraction out of a hundred.
Ratio - Shows the relationship between part to part that when added gives you part to whole.

Yeah, I'm done now (: By the way, this took me FOREVER because of some technical difficulties with google and stuff. So sorry if it's posted this late !

NEXT SCRIBE IS VANESSA LY (:

Woah. Now the scribes should be thinking twice about what they write, keeping in mind that we have thousands and thousands of people viewing and learning something off of our posts.
