How is multiplying fractions by a whole number is different from adding adding and subtracting fractions with like denominators?
Adding and subtracting fractions can ONLY be done if the denominators are the same; then the calculation is done by adding or subtracting the numerators. Multiplying (and dividing) fractions does not require the denominators to be the same. To divide by a fraction the divisor is inverted (the original numerator becomes the new denominator and the original denominator becomes the new numerator) and then the fractions are multiplied. Multiplying fractions is achieved by multiplying the numerators together AND multiplying the denominators together. A whole number is the same as a fraction with the whole number as the numerator and a denominator of 1, so when multiplying by a whole number the denominator is multiplied by 1 (leaving it the same) and the is multiplication is effectively just multiplying the numerator by the whole number.
What is a subtracting mixed number?
Subtracting a mixed number is just subtracting fractions but with a whole number by a fraction. To subtract tun the mixed numbers into improper fractions and find the common denominator. Then you subtract the numerators.
How sustract fractions?
Determine the lowest common denominator. Multiply the numerator and denominator of each fraction by a number that will result in the denominator becoming the LCD. The purpose for multiplying both the numerator and denominator is that any number divided by itself = 1, and when you multiply something by 1, you don't change it. When subtracting two fractions with the same denominators, the first numerator minus the second numerator equals the numerator of the result, and the result has the same denominator (the LCD). Simplify.
How do your borrow from a whole number when subtracting fractions?
A mixed number has a whole number and a fraction. A fraction is a number that is less than whole and that has a denominator underneath a numerator. To add or subtract mixed numbers, add or subtract the fractions, then add or subtract the whole numbers. If the fraction portion of a mixed number, such as 2 5/6, is more than the fraction portion of the mixed number you're trying to subtract from, such as 3 1/6, you must borrow from the whole number of the mixed number you're trying to subtract from to make its fraction bigger...

How do you subtract mixed numbers and borrow from the whole number?
you subtract mixed numbers by changing them to improper fractions. to borrow from a whole number you take away one like 5 changes to 4 and then you change look to the other mixed number your subtracting by and write its denominator as 4s denominator.
How do you do equivilant fractions?
Multiply the numerator and the denominator by the same number or divide the numerator and the denominator by the same number
How do you do fractions when asked find fractions?
example: 1/4 the fraction is made up of a numerator, denominator, and vertice the numerator is the number being divided by the denominator or the number on top of the vertice the denominator is the divisor or the number below the vertice the vertice is the line in the middle of a fraction, separating the denominator and numerator
How do you divide fractions when there is a whole number?
you divide by the denominator and times by the numerator
How do you covert fractions into decimals?
You divide the numerator (the top number) by the denominator (the bottom number)
How can fractions be written as a decimal?
Divide the numerator (top number) by the denominator (bottom number).
How do you do subtracting fractions with regrouping?
You do by subtracting one from the previous number and adding 10 to the top number of the digits you are regrouping. Subtract those two digits and you should get your answer.
Why are all fractions with a numerator of 1 in simplest form?
All fractions with a numerator (top number) of 1 are in simplest form because 1 is the smallest whole number there is and cannot be divided into anything smaller and still be a whole number.
