Just multiply the two denominators of your fractions, the answer you get is a common denominator.
You Ned to find a larger common denominator or multiply the denominators to gain a common denominator.
You DO need a common denominator to add, subtract, or compare fractions. You DO NOT need a common denominator to multiply or divide fractions.
It helps to find a common denominator and multiply both sides of the inequality by this common denominator. That way, you have an inequality without fractions.
yes. you multiply the numerator and denominator
multiply denominator by denominator and vice versa
Option 1: Find a common denominator for the two fractions. It need not be the least common denominator; for example, for two fractions, if you just multiply the two denominators, you get a common denominator. Convert all the fractions to the common denominator. Then you can compare. Option 2: Convert each fraction to decimal, by dividing the numerator by the denominator. Then you can compare the decimals.
multiply the two denominators
Yes you do.
First, find a common denominator for the two (or more) fractions. Then, for each fraction, multiply numerator and denominator by the same number (different numbers for different fractions, though), to convert to the common denominator.
To make the denominator of two fractions the same, you multiply numerator and denominator of one fraction of the fractions by the same number. You may also have to multiply numerator of the other fraction by a different number.For example, to add 1/8 + 1/10, you have to convert to a common denominator; the lowest common denominator is 40, but any common denominator will work (for example, 80 which is simply the product of the two).To convert 1/8 to a fraction with a denominator of 40, multiply numerator and denominator by 5. To convert 1/10, multiply numerator and denominator by 4. The result is:5/40 + 4/40
no u dnt need to have a common denominator.. Just multiply both the denominator and numerator of the fractions u are working on and u will arrive at the answers
The first step, to add, subtract, or compare fractions, is always to convert the fractions to equivalent fractions, that all have the same denominator. You can use one of several techniques to get the LEAST common denominator, or simply multiply the two denominators to get a common denominator (which in this case may, or may not, be the smallest common denominator).
Assuming the fractions are "normalized" (the fractional part is less than 1): First compare the integer part. If the integer part is the same, you need to compare the fractions. If the denominator of the fractions is different, you have to convert to a common denominator. The simplest way to find a common denominator is to multiply both denominators (i.e., you don't need the LEAST common denominator - any common denominator will do).
no. you can multiply straight across in fraction multiplication
You have to find a common denominator, multiply them, subtract them and then simplify if you need to.
It is easier to multiply or divide fractions than to add or subtract fractions because in multiplication, you just have to multiply the numerator by the numerator and the denominator by the denominator. Same applies with division of fractions, except that you have to reciprocate the fraction you're dividing with (divisor) then proceed to multiplication. Whereas, in addition and subtraction of fractions, you still have to get their Least Common Denominator (LCD).
Multiply every term in the equation by a common denominator of all the fractions. The least common denominator (if different) will result in smaller numbers that you then have to work with but it is not essential that you use it.
find a common denominator. multiply the top and bottom by it. then you can combine the numerators over the same denominator
Exactly the same as you do when multiplying fractions with different denominators. -- Multiply numerators . . . the product is the numeratore of the answer. -- Multiply denominators . . . the product is the denominator of the answer.
