How do you subtract fractions with different denominators?
Subtracting Fractions with Unlike Denominators
To do this, you need to find the least common multiple (LCM) of the two denominators. To subtract fractions with unlike denominators, rename the fractions with a common denominator. Then subtract and simplify.
How do you equalize fractions?
- You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount.
- You only multiply or divide, never add or subtract, to get an equivalent fraction.
- Only divide when the top and bottom stay as whole numbers.
What is the rule for fractions?
To add or subtract fractions they must have the same denominator (the bottom value). If the denominators are already the same then it is just a matter of either adding or subtracting the numerators (the top value). If the denominators are different then a common denominator needs to be found.
What are 5 fractions equivalent to 2 3?
Answer: 4/6, 6/9, 8/12, 10/15 ... are equivalent to 2/3. All those fractions obtained by multiplying both the numerator and denominator of 2/3 by the same number are equivalent to 2/3.
Do you add or multiply fractions first?
The first step when multiplying fractions is to multiply the two numerators. The second step is to multiply the two denominators. Finally, simplify the new fractions. The fractions can also be simplified before multiplying by factoring out common factors in the numerator and denominator.
What fractions are equal to 3 6?

How do you add and multiply fractions with different denominators?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
How do you estimate dividing fractions?
The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.
How do you know if fractions are similar?
If the denominators are the same, then the fraction with the greater numerator is the greater fraction. The fraction with the lesser numerator is the lesser fraction. And, as noted above, if the numerators are equal, the fractions are equivalent.
How do you simplify fractions step by step?
- Write down the factors for the numerator and the denominator.
- Determine the largest factor that is common between the two.
- Divide the numerator and denominator by the greatest common factor.
- Write down the reduced fraction.
How do you convert fractions into hours and minutes?
- Given: (i) The fraction is in hours.
- To find: (i) The fraction in minutes.
- Solution: We know that 1 hour = 60 minutes. So, for example, of we take an improper fraction, like hours. Converting it in minutes, we do by multiplying with 60. So, hours = ( × 60) minutes.

Are Remainders the same as decimals?
Basically, when we're using remainders, we don't bring in any decimals—a remainder provides a way of looking at division with only integers. Let's look at a simple example to show the relationship between decimals and remainders. Remainder Answer: 7/2 = 3 R1.
How do decimals work?
Decimals are a shorthand way to write fractions and mixed numbers with denominators that are powers of 10 , like 10,100,1000,10000, etc. If a number has a decimal point , then the first digit to the right of the decimal point indicates the number of tenths. For example, the decimal 0.3 is the same as the fraction 310 .
