How can finding the least common multiple of two numbers help you add fractions?
When you have fractions with unlike denominators, it is necessary to find a common denominator before you add or subtract them. The process is the same as finding an LCM, but since the numbers are denominators, we call it the least common denominator. Example: 1/3 + 1/4 The LCM of 3 and 4 is 12. 1/3 = 4/12 1/4 = 3/12 1/3 + 1/4 = 7/12
What is the episode when frasier is interrupted before a date by martin niles and daphne?
there are about 50 episodes that, that happens you have to explain more

What other evidence could explain how day and night occured when the tilt of earth's axis happened?
The Earth was probably rotating before that because not to rotate is a special case that is unlikely to occur.
What are some playstation network card numbers?
Card numbers are redeem codes and are no longer of value after redemption. I could provide a huge list of ones I have already redeemed, but what could you do with them It's like gift cards before the money is added or after it has been spent
How is multiplying mixed numbers different than multiplying fractions?
if you have mixed numbers you make them into improper fractions before you multiply
Is there a trick to multiplying mixed numbers?
you have to turn them into improper fractions before you multiply them.
Why do you change mixed numbers to improper fractions before multiplying and dividing?
Because common denominators allow adding and subtracting of numerators. Improper fractions also have simplified rules over mixed numbers when performing multiplication and division.
When asked to find the sum of two mixed numbers with different denominators you should before you add?
Convert the fractions into equivalent fractions with the same denominator. In actually adding mixed numbers, it is easier to convert the mixed numbers into improper (top heavy) fractions, do the addition, simplify the resulting fraction and convert any resulting improper fraction back into a mixed number.
Before adding or subtracting two fractions they are converted into like fractions Explain with examples why this is necessary?
Before adding or subtracting two fractions they are converted into like fractions. Explain with examples why this is necessary.
How do you change mixed numbers before multiplying improper fractions?
To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator. 3 and 1/7 = 22/7
How do you sum two mixed numbers with different denominators?
Before you can do that, you need to write each mixed number as an improper fraction, and then write both fractions with a common denominator. The only other choice is to write both mixed numbers as decimals, and then add them.
How do you divide mixed numbers with like denominators?
Written as improper fractions, divide the numerators (converting any resulting improper fraction to a mixed number if required).However, I would rather not remember this short cut as it could result in being used inappropriately (when the denominators are different), but instead stick to using the standard method, writing out the calculation in full and cancelling down before doing the actual multiplications.The same way as mixed numbers without like denominators:Convert the mixed numbers into improper (top heavy) fractions.Invert (turn upside down) the divisor.Multiply the fractions together (by multiplying the numerators together and the denominators together).However, with the same denominators, in inverting the divisor it will mean that its numerator is the same as the denominator of the [original] dividend and so will cancel, leaving the result as the numerator of the first improper fraction over the numerator of the second - dividing the improper fractions' numerators.
What do you do when you are dividing a fraction?
When dividing a fraction you leave the first fraction as it is and you change the second fraction into a reciprocal (flip the fraction). Once you have changed the second fraction into a reciprocal, then you would simply *multiply the two fractions together. Once you multiply the two fractions then that would be your final answer. Dont forget to simplify! And remember if the fractions are mixed numbers before you do anything you must change the mixed numbers into improper fractions first! hope this helps! *If you dont know how to multiply fractions then thats a different question
Why do you change mixed numbers to improper fractions before you divide?
Well unless the whole number can be divided evenly by the divisor, a fraction would be left over before dividing the fraction by the divisor. It is much easier in these cases to create a top-heavy fraction
Why do you have to change a mixed number to an improper fraction before multiplying mixed numbers?
You don't.
What are foundations for fractions?
for calculations including parts of numbers, before decimals were commonplace
