C = F-32 x .5556 or F° minus 32 times 5/9 To convert temperatures in degrees Fahrenheit to Celsius, subtract 32 from F° and multiply by . 5556 (or 5/9). Subtract Fahrenheit & Multiply by .5556 Ex. (50 Fahrenheit - 32) * .5556 = 10 Celsius What is the decimal equation to convert Celsius to Fahrenheit? C ° times 9/5 plus 32 1 quart = ounces 32 How to convert a fraction to percent? Divide the top of the fraction by the bottom, multiply by 100 & add % sign. Ex. 2/3 = 66.7% change the fraction to a percent 5/9 Change the fraction into a division problem and solve .Move the decimal behind the hundredths place in the quotient. .Drop the percent sign after the new number. 55.5% How to convert a percent to fraction? Step 1: Write down the percent divided by 100 like this: percent/100 Step 2: If the percent is not a whole number, then multiply both top and bottom by 10 for every number after the decimal point. (For example, if there is one number after the decimal, then use 10, if there are two then use 100, etc.) Step 3: Simplify (or reduce) the fraction Ex. 75% = 75/100 = 15/20 = 3/4 Convert 62.5% to a fraction Ex. Step 1: write down. 62.5% = 62.5/100 Step 2: multiply both top & bottom by 10. = 62.5/100 *10 = 625/1000 Step 3: Simplify the fraction. 625/1000 Divided by 25 = 25/40 can go lower if divided by 5 which = 5/8 A sample contains 2/3 oz. of liquid. How many milliliters (mL) is this? To convert oz. to mL, multiply by 30 oz./mL. 2/3 * 30 = 60/3 = 20 Instructions require you to dilute a powder in 3 quarts of water. You only have a container that is marked in liters. How many liters would you use to dilute the powder? 1 Quart = 32 oz Therefore, 3 Quarts = 96oz. There are 30 milliliters per oz., so 96 oz 2,880 milliliters There are 1000 milliliters per liter, so 2, mL = 2.88 Liters Or 1 Quart = 0.946 Liter *3= 2.838 = 2.88 . = 880 L 35% to fraction 35/100 = 7/20 1 foot = 30.48 centimeters or 0.3048 meters 1 yard = 0.914 meters 1 mile = 1.609 kilometers 1 ounce = 28.350 grams 1 pound = 454 grams or .454 kilograms 1 fluid ounce = 29.574 milliliters 1 Quart = 0.946 liters 1 Gallon = 3.785 liters 1 Pound = 16 fluid ounces 10 kilograms is equivalent to how many pounds? to convert kilograms to pounds, multiply 2.2 lbs/kilo. 10 * 2.2 = 22 How to convert Celsius to Fahrenheit? Multiply Celsius by 1.8 & add 32. Ex. 30 Celsius * 1.8 + 32 = 86 Fahrenheit How to convert Fahrenheit to Celsius? -Subtract Fahrenheit & Multiply by .5556 Ex. (50 Fahrenheit - 32) * .5556 = 10 Celsius what is the reciprocal of 6? 6/1 = 1/6 In class the ratio of males to females is 4:5. If there are 36 total students, how many females are in the class? Males= 4 Females= 5 Total= 9 How many times does 9 go into 36? 4. so multiply 4 by each male, female, and total. male= 4*4= 16 female= 5*4= 20 total= 9*4= 36
