Solve the algebraic equation

1) 5 = k + 2 2) 4y - 3= 9 3) a +4 = 15 4) 3n - 4 = 14

5) 7 k=14 6) c/7=3 7) 7=p/3 8) 6/j+2=10

/ means divide

Finding the mean , median and mode for each question

1) 3,34,6,6,8,7,,11,4,6 2) ,9,12,14,15,2,1,5,4,5,7,7,

3),1,2,4,6,3,4,2,2 4) 7,3,2,5,14,3.8.17,28 5) ,4,1,5,7,11,13,5,7,8,9

Mesures Of Central Tendency

Common Denominators

A common multiple of the denominators of a set fractions

A common denominator for 1 over 4 and 1 over 6 is 12 because a common multiple of 4 and 6 is 12



Multiples ( skip count )



The product of a given number and a natural number like 1,2,3 and so on



For example some multiples of 3 are 3,6,9,12



1x3=3 ,2x3=6, 3x3=9,3x4=12



List 5 multiples of 4



Don't find factors



4,8,12,16,20,24



1 over 2 and 2 over 3 find common denominator

(find multiples first than find LCF )



multiples of 2 are 2,4,6,8,10 multiples of 3 are 3,6,9,12,15



The LCF is 6 so



1 x3 3

2 x3 6 What you do to the bottom you must do to the top



2 x2 4

3 x2 6 What you do to the bottom you must do to the top

Sorry guys I could add a picture or a video

Subtracting Fractions with Like Denominators

Subtracting Fractions with Like Denominators

When subtracting fractions its like adding fractions but insted you subtract the numerator NOT the denominator.

Here is an example we did in class...

And you see that the denominator did not change.

Here is an example of subtracting decimals but using pictures....

Here are some of the homework questions.....

That is how to subtract decimals and remember don't ever change the denominator when adding or subtracting decimals.

Math notes for lowest terms

LOWEST TERMS-A fraction is in lowest terms when the numerator and denominator of the fraction have no common factor other than 1

Probability Answer for Charisse

Her question was :

Clarisse picks all the blue smarties out of all 21.
She also has a spinner to who she'll give the blue smarties too.
1. Put all the outcomes of these two events in a table or which ever you'd like.
2. What is the Sample space?
3. Are the Outcomes independent?

My Answers:

-The circled possible out

comes are the Sample Space

-Yes , The outcomes of one e

vent as no effect on the other .

BY THE WAY .. Nice question Charisse (;
