First we need a common denominator the easiest is 35 (since 5 x 7 = 35) Now convert both fractions to the common denominator 3/5 x 7/7 = 21/35 3/7 x 5/5 = 15/35 Now we just add the the 2 fractions together: 21/35 + 15/35 = 36/35 So the final answer is 36/35

To compare two fractions, find a common denominator (multiplying the two denominators will always give you a common denominator), convert both fractions to the common denominator, then compare. Another - actually easier - way to compare two fractions is to convert both to decimal. Just pick up a calculator, and divide the numerator by the denominator.

The Least Common Denominator of 57 and 35 is 1.

The least common denominator for 4/5 and 31/35 is 35.

There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions.

The Least Common Denominator of 5, 7, and 35 is 1.

The factors of 35 are 1, 5, 7, and 35. In order to find a common denominator, you would need another number for it to be in common with.

It is 35/100.

If those are both denominators, multiply their fractions by 10/10 to get rid of the decimal points. The LCD of 35 and 14 is 70. Convert them to equivalent fractions with a denominator of 70.

35 is.

Least common denominator of 7 and 5 is 35.

Lowest common denominator of 50 and 35 is 350.

A common denominator, though not the least, is 1680.

The greatest common denominator is infinite.

lcd = lowest common denominator. are these denominators of fractions, if so the lcd (since they have no common factors) is 8x35 = 280 if you mean lowest common divisor then the answer is 1

Two fractions having different denominators cannot be added or subtracted directly. They need to be converted to equivalent fractions having the same denominator to enable the addition or subtraction to take place. It is possible to use the product of the denominators of the original fractions as the common denominator but it simplifies the mathematics if the lowest common multiple of the two denominators is used. EXAMPLE : Add 2/5 and 3/7. The lowest common denominator (also the LCM) of 5 and 7 is 35. 2/5 is equivalent to 2 x 7/5 x 7 = 14/35 : 3/7 is equivalent to 3 x 5/7 x 5 = 15/35 2/5 + 3/7 = 14/35 + 15/35 = 29/35

To get the correct answer. If you were adding 1/5 and 1/7, you might not know that the answer is 12/35 unless you knew that 1/5 = 7/35 and 1/7 = 5/35

35 is.

You divide or multiply the denominator and numerator of the fractions in order for the denominators to match. For example: We have the two fractions 5/6 and 4/7. We can multiply the first fraction's numerator and denominator by 7 to get 35/42. We can multiply the second fraction's numerator and denominator by 6 to get 24/42. Therefore we would then have 35/42 and 24/42 with matching denominators.

4/7 - 2/5 = 6/35. To subtract (or add) fractions make both fractions equivalent fractions with the same denominator. The LCM (Lowest Common Multiple) of 7 and 5 is 35, so convert both the fractions to equivalent fractions out of 35: 4/7 = 20/35 2/5 = 14/35 The subtraction can now be done: 4/7 - 2/5 = 20/35 - 14/35 = 6/35

It is infinity but the lowest common denominator is 3185

Convert both fractions into equivalent fractions having the same denominator. The value of this common denominator can be obtained by multiplying together the original denominators or there may be a Lowest Common Multiple that can be used. EXAMPLE: 4/5 - 3/7 : The common denominator is 5 x 7 = 35 4/5 = 28/35 : 5 divides into 35 seven times, so the numerator and denominator have both been multiplied by 7 to produce an equivalent fraction. 3/7 = 15/35 : As above, but in this case 7 divides into 35 five times, so 5 has been used as the multiplier. 28/35 - 15/35 = 13/35 : If the fraction could be simplified then at this stage this would be done. In practice, the above stages would be merged so that the calculation becomes :- 4/5 - 3/7 = (7x4) - (5x3) ÷ 35 = (28-15)/35 = 13/35

The lowest common denominator of any two or more whole numbers, such as 35 and 48, will always be one (1) because 'common denominator' refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.
