**California Blue Prints**

Number Sense 25 39% Standard Set 1.0* Students compare and order positive and negative fractions, decimals, and mixed numbers. Students solve problems involving fractions, ratios, proportions, and percentages: 1.1* Compare and order positive and negative fractions, decimals, and mixed numbers and place them on a number line. 3 1.2* Interpret and use ratios in different contexts (e.g., batting averages, miles per hour) to show the relative sizes of two quantities, using appropriate notations (a/b, a to b, a:b). 1 1.3* Use proportions to solve problems (e.g., determine the value of N if 4/7 = N/21, find the length of a side of a polygon similar to a known polygon). Use cross- multiplication as a method for solving such problems, understanding it as the multiplication of both sides of an equation by a multiplicative inverse. 6 1.4* Calculate given percentages of quantities and solve problems involving discounts at sales, interest earned, and tips. 5

**How to find the sales tax!**

First find out what tax rate you will be paying. In California the tax rate is 8.25%! Convert your percentage to a decimal by moving your decimal two spaces to the left. Ex % = (Don’t forget to add a zero) Multiply the decimal form of the tax rate by the price of the item you are purchasing. Ex x $ cost of the item

**How to find the sales tax!**

So if an item costs $5.00 Sales tax is 8.25% Convert 8.25% to .0825 So x $5 = $.41 The sales tax is $.41 But the total price of the item is $ $.41 = $5.41

5
**How to find the Discount & Discounted Price**

Find out the % of the discount. Convert the % to a decimal. Multiply the decimal by the original price. Take the answer in step 2 and subtract it from the original price. Example Discount 20% = .20, $10 x .20 = $2.00 $ $2.00 = $8.00
