A dding and Subtracting Integers and Unit Rate Prices By:Erica and Lewis

Unit Rate Price Cross Multiply & Divide 1.you have to solve with the money they give you. 2.what is the price ? 3. you have to cross multiply with the price it is going to always be one because you wanna know how much 1 cost. 4.The first answer you get you are going to divide by the number that you have not used. $10.00 X 5 1 $10.00 x 1 = $10.00 $ = 2 x = 2

Unit Rate Price Mrs. Jenkins is going to the store to get 3 packs of Diet Coca Cola for $ $ X 3 packs 1 Cross Multiply and Divide $10.00 x 1 = $ = $3.33 each pack X = $3.33 each pack

unit rate Price Mrs.Batten has to buy 2 bags of hershey kisses candy for $6.00. $6.00 X 2 1 $6.00 x 1=$ = 3 X = 3 each bag

Adding and Subtracting Integers Adding Integers you have to do a T chart.Then who wins? by how many? Subtracting Integers you have to do Keep,Change,Change.Then T chart

Adding Integers (-10)+5= -5 who wins? -10 by how many? 5 If they are on the same side If they are on different side 5 -10

Subtracting Integers K C C 12-(-21)= 12+(+21)= Keep,Change,Change + 33 then you do T chart
