Two measurements often used interchangeably are?
Cubic centimetres and millilitres.
Why is the data that scientists gather typically in mathematical figures?
Data is often measurements, which are expressed in numbers
What are the uses for fractions?
Measurements (think tools and carpentry) They also develop in equations and formulae E.g. Distance = Speed X Time, or D = ST Therefore S = T / D or T D (Meant to be an underscore under the T but it's not available.) You can often use fractions as a division method, by factors and cancelling. Eg: 288/48 = 144/24 = 72/12 = 6. I simply divided the numerator and denominator by 2 until I gained a division easily carried out mentally.
What is ratio and proportion?
A ratio, similar to a proportion, is the value of one number or measurement in relation to another, and is often symbolized as x:y, x/y, or "x to y." Conceptually, ratios can be thought of as fractions and are often simplified the same way. For instance, if a cocktail recipe calls for 2 oz. of liquor for every 4 oz. of juice, the ratio of liquor to juice is 2:4, 2/4, or "2 to 4." However, 2:4 will almost always be simplified, in a similar way that fractions are, and written as 1:2. The main difference between the simplification methods of ratios vs. fractions is that for fractions, a value such as 10/6 will often be reduced to 1 2/3, whereas ratios will never pull an integer out of a fraction like that. In this particular case, the ratio would be 5:3, 5/3, or "5 to 3," not 1 2/3:3. The subtle, but meaningful difference in the usage of the terms proportion and ratio is that proportions often imply the combined totality of the two values or measurements you're relating as opposed to ratios, which are used to describe the values' relative independence. For example, you would say, "equal proportions," "directly proportional," and "inversely proportional," but you wouldn't say, "equal ratios," "directly rational," or "inversely rational."
What is one step when multiplying fractions?
Multiplication of fractions is similar to multiplication of whole numbers. Often, multiplication of fractions can be made easier by first performing cancellation. Cancellation involves dividing both a numerator and a denominator by the same number. This is the same as dividing a fraction by one, and so it does not alter the answer. When cancelling, cross out the old terms and write in the new terms.
How are fractions used in math?
Often in Math, fractions are used to add, subtract, multiply, divide, or indicate the magnitude of measurements that will be involved in those operations. They can be used as numbers whenever the authentic number is not an integer.
When should you convert metric measurements to standard US measurements?
as often as possible
What is almost the same as 25 grams?
25g is approximately 1 oz This is often used for easy conversion of recipes from imperial to metric measurements. A more accurate conversion is 1 oz ~= 28.35g
What is often included in a science experiment?
measurements
Which of these are often included in scientific experiments?
measurements
When do you use LCM?
When you are trying to add or subtract unlike fractions.
How do you simplify 1.37?
Fractions can often be simplified, but numbers never can.
Do you solve equations any differently if they contain fractions?
Not necessarily, but often it is simpler to convert fractions into decimals to solve the equation.
What you do when you multiplying fractions it is often necessary to the result to lowest terms?
reduce
