*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 )

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

Wow Vanessa. Great Scribe. Your use of minimal colour changes makes it easy to see the different sections of this scribe. You have tremendous detail. To make this scribe even greater you need to add some links to helpful sites and perhaps some questions for students to answer. YOu could use some of the examples from your homework!!

Great Job

Harbeck

Great scribe Vanessa. Hope your foot heals really good!!

hey

Great Scribe...it was very neat and organized
