What two fractions have a common denominator of 8?
One of the fractions must have the denominator 8. The other could have a denominator of 2, 4 or 8.
Why are equivalent fractions important when adding and subtracting fractions?
Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.
How do you solve a fraction problem when you don't have the same denominator?
If you are adding or subtracting unlike fractions, convert them to equivalent fractions with a common denominator.
How do you compare 3 or more fractions?
Find the equivalent fractions with the same denominator (the least common multiple) and then compare the numerators.
How do you arrange the fraction from greatest to least?
With certain fractions then experience and observation will enable them to be placed in descending order. With fractions where the order is difficult to assess then they will need to be converted to equivalent fractions having the same denominator. A direct comparison of the numerators will then enable the original fractions to be placed in order. EXAMPLE : Arrange 5/6. 8/9 and 7/8 in descending order. The Lowest Common Multiple of 6, 8 and 9 is 72. This is the new common denominator. 5/6 is equivalent to 5x12/6x12 = 60/72 : 8/9 is equivalent to 8x8/9x8 = 64/72 : 7/8 is equivalent to 7x9/8x9 = 63/72. Therefore the descending order is 64/72,63/72,60/72 or 8/9, 7/8, 5/6
Is 3 over 4 or 5 over 8 bigger?
To compare fractions, convert them to a common denominator - in this case, a denominator of 8 will work.To compare fractions, convert them to a common denominator - in this case, a denominator of 8 will work.To compare fractions, convert them to a common denominator - in this case, a denominator of 8 will work.To compare fractions, convert them to a common denominator - in this case, a denominator of 8 will work.
What are three equivalent fractions of 7 over 8?
equivalent factors are fractions where the numerator and denominator are multiplied by the same number, so equivalent fractions of 7/8 by 2,3, and 4 are (14/16, 21/24, and 28/32)
What is 5 over 8 minus 1 over 4 equal?
5/8 - 1/4 = 5/8 - 2/8 = 3/8 (make all fractions equivalent fractions with a common denominator - in this case, a common denominator of 8 - and then subtract the numerators).
What do you do when comparing fractions and the denominator and the numerator are different?
Convert them into equivalent fractions with the same denominator and then compare the numerators.
Find a common denominator for the pair of fractions. Then, write equivalent fractions with the common denominator?
Find google
Can you call 2 equivalent fraction like fractions?
No. Like fractions have the same denominator.
How do you add fractions with unlike denometiors?
You look for a common denominator; convert the fractions to equivalent fractions with the denominator you found; then you do the addition itself.
Two fractions have a common denominator of 8 what could the fractions be?
Any fractions with a denominator of 8. Also, the denominator of one of the fractions might be any factor of 8.
What two fractions have a common denominator of 8?
One of the fractions must have the denominator 8. The other could have a denominator of 2, 4 or 8.
How can you tell if fractions are equivalent?
Divide the denominator into the numerator. If the answers are the same decimal, the fractions are equivalent.
Adding and subtracting unlike denominators?
Fractions can only be added or subtracted if the denominators are the same. If the denominators are different, then the fractions need to be made into equivalent fractions with the same denominator. The new denominator can be found simply by multiplying the denominators together, but this can lead to some large fractions with which to work. A better new denominator is the lowest common multiple of (all the) denominators. (Once the new denominator is found, the fractions' new numerators are found by multiplying their current numerator by the new denominator divided by their current denominator to make their equivalent fractions with the new denominator.) Once all the fractions are converted into equivalent fractions with the new denominator then the fractions can be added or subtracted, with the result being simplified (if possible).
Is 3 out of 8 equivalent to 9 out of 24?
Indeed, since you have multiplied both the numerator and denominator by the same number, 3/8 and 9/24 are equivalent fractions.
