How do you put different fractions in increasing order?

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.

Find their lowest common denominator and adjust their numerators accordingly and then add them together. By dividing the sum by 2 will give you the halfway result


How do you order fractions from least to greatist?

Two ways: You can find a common denominator, convert them to equivalent fractions and line up the numerators or you can convert them to decimals by dividing the denominator into the numerator and line them up numerically. The second way is easier.


Adding unlike fractions?

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.


Find a fraction between each pair of fractions?

An easy method for finding a fraction between two fractions would be to take the average of two fractions. You find the average by adding the two fractions together and then dividing the final sum by 2.

How can using the GCF and LCM help you when you add subtract and multiply fractions?

When adding and subtracting unlike fractions, it is necessary to find a least common denominator. It's the same process as finding an LCM. You can simplify a fraction by finding the GCF of the numerator and denominator and dividing them both by it.
