VANESSA'S SCRIBE

Today we spent most of the class writing this in our math notebooks:

FRACTIONS
Converting Fractions to Decimals
Divide the numerator by the denominator to get the decimal.
N/D=decimal
e.g.
¾ → 3 / 4 = 0.75

Converting Fractions to Percents
There are two possible ways:
Multiply the numerator by 100 and divide it by the denominator.
N x 100 / D = Percent
e.g.
¾ → 3 x 100 = 300
300 / 4 = 75%
OR
Divide the numerator by the denominator and multiply by 100.
N / D x 100 = Percent
e.g.
¾ → 3 / 4 = 0.75
0.75 x 100 = 75%

Converting Fractions to Ratios
Part 1 : Part 2
Part 1 is the numerator.
Part 2 is the numerator subtracted from the denominator.
N : D-N
e.g.
¾ → 3 : 1

DECIMALS
Converting Decimals to Fractions
Say the decimal then write it.
e.g.
0.42 (forty-two hundredths)
42/100

Converting Decimals to Percents
Multiply the decimal by 100
e.g.
0.42 x 100 = 42%

Converting Decimals to Ratios
Convert the decimal to a fraction first.
e.g.
0.42 → 42/100
Part 1 in the ratio is the numerator.
Part 2 in the ratio is the numerator subtracted from the denominator.
N/D → N : D - N
e.g.
0.42 → 42/100
42 : 58
.........^100 - 42 = 58

PERCENTAGES
Converting Percents to Decimals
Divide the percent by 100.
% / 100
e.g.
57% / 100 = 0.57

Converting Percents to Fractions
The percent is already out of 100, so the denominator will be 100.
The actual percent is the numerator.
e.g.
57% → 57/100

Converting Percents to Ratios
Part 1 is the actual percent
Part 2 is 100 subtracted by the percent
................(100 - % )
e.g.
57% → 57 : 43
......................^ 100 - 57 = 43

RATIOS
Converting Ratios to Fractions
Part 1 + Part 2 = denominator
Part 1 = numerator
e.g.
7 : 3 → 7/10

Converting Ratios to Decimals
First convert the ratio to a fraction.
e.g.
7 : 3 → 7/10
Numerator is 7 because its Part 1. Denominator is 10 because part 1 + part = 10 ( 7 + 3 = 10 )
Then divide the numerator by the denominator to get the decimal
N / D = Decimal
e.g.
7 / 10 = 0.7

Converting Ratios to Percents
First convert the ratio to a fraction.
e.g.
7 : 3 → 7/10
Numerator is 7 because its Part 1. Denominator is 10 because part 1 + part 2= 10 ( 7 + 3 = 10 )
Then divide the numerator by the denominator to get the decimal
N / D = Decimal
Next multiply the decimal by 100 to get the percent
Decimal x 100 = percent
e.g.
7 / 10 = 0.7
0.7 x 100 = 70%

After you've finished copying the above information into your notebook, you need to write it again in the big paper, in rows 4 and 5.

Then we spent the last 15 minutes working on " Equivalents the Assignments. "

HOMEWORK
"Equivalents the Assignment"
4 questions, Mr. Harbeck already posted it (scroll down to last post)

Stuff we did so far and need to be completed (portfolio):
1. Equivalent Chart
2. Big Paper
3. Quiz
4. Equivalent Assignment
