Convert them into equivalent fractions with the same denominator and then compare the numerators.
You can either convert fractions to decimals and compare the decimal numbers; find equivalent fractions with the same denominator and then compare numerators or find equivalent fractions with the same numerator and then compare denominators.
Comparing fractions is easiest with a common denominator. Then only the numerators need to be compared. Take 8/40, and divide numerator and denominator by 4 : 8/40 = 2/10. Now compare 2/10 and 6/10 is the same as comparing 2 and 6, so 6/10 is bigger.
Well, darling, comparing fractions with the same denominator is a piece of cake. Just look at the numerators - the bigger one means the fraction is bigger, the smaller one means the fraction is smaller. It's like comparing apples to oranges, except in this case, they're both fruits, so it's pretty straightforward.
You can convert them to equivalent fractions with like denominators, then simply compare the numerators.You might also convert each fraction to a decimal (divide the numerator by the denominator); then you can also compare them.
Convert them into equivalent fractions with the same denominator and then compare the numerators.
Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).
you compare them
You can either convert fractions to decimals and compare the decimal numbers; find equivalent fractions with the same denominator and then compare numerators or find equivalent fractions with the same numerator and then compare denominators.
Rule #1 When two fractions have the same denominator, the bigger fraction is the one with the bigger numerator. Rule # 2 When comparing fractions that have the same numerator, the bigger fraction is the one with the smaller denominator. Rule # 3 You can convert the fractions and then just put the greater than, less than or equal to sign to see what the comparison is between the fractions.
The same numerator or the same denominator.
Find the equivalent fractions with the same denominator (the least common multiple) and then compare the numerators.
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).
If the fractions have different denominators, you need to: 1) Convert to equivalent fractions with a common denominator, 2) Compare the numerators. If the fractions already have the same denominator, there is no need for the first step - which happens to be the most difficult step. Note that as a shortcut, you don't need the LEAST common denominator, any denominator can do. Thus, you can just use the product of the two denominators as the common denominator. As a result, to compare the fractions, you simply multiply the numerator of each fraction by the denominator of the other one, and then compare. However, this is still more work than simply comparing two numbers.
It depends on how you need to compare them. If you want to know which one is larger, just look at the denominator - a smaller denominator means a larger number. If you need to add or subtract them, the only thing you can do is make the denominators equal.
We can only add or subtract fractions if they have the same denominators
The fractions can be ordered according to the order of their numerators.
