What do you do when comparing fractions and the denominator and the numerator are different?
Convert them into equivalent fractions with the same denominator and then compare the numerators.
How do you compare fractions?
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.
What is bigger 8 over 40 or 6 over 10?
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.
How do you order fractions with unlike denominators?
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.
Is 0.7 greater than 7 over 9?
7/9= 0.777... so no. ----------------------------------------------------------------- Alternatively, working with fractions: Convert to fractions with the same denominator and compare the numerators: 0.7 = 7/10 = (7×9)/(10×9) = 63/90 7/9 = (7×10)/(9×10) = 70/90 70 > 63 → 70/90 > 63/90 → 7/9 > 0.7 → No, 0.7 is less than 7/9 Instead of converting to equivalent fractions with the same denominator to compare numerators, if (and only if) the numerators are the same, the fractions can be compared by comparing the denominators and the fraction with the larger denominator is the smaller fraction: 0.7 = 7/10 7/9 same numerators, so compare denominators: 10 > 9 → 7/10 < 7/9 → 0.7 < 7/9 → No, 0.7 is less than 7/9
What do you do when comparing fractions and the denominator and the numerator are different?
Convert them into equivalent fractions with the same denominator and then compare the numerators.
Explain how comparing fractions with like denominators differs from comparing fractions with unlike denominators?
Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).
How can you compare fractions of the same whole?
you compare them
How do you compare fractions?
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.
What are three rules you can use to compare fractions?
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.
What do fractions need to have to compare them?
The same numerator or the same denominator.
How do you compare 3 or more fractions?
Find the equivalent fractions with the same denominator (the least common multiple) and then compare the numerators.
How do you use comparing mixed fractions?
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).
Why is it easier to compare fractions with the same rather than denominator?
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.
What are some rules about comparing fractions with the same numerator?
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.
How do you compare fractions with the same denominator but different numerators?
The fractions can be ordered according to the order of their numerators.
Fractions can be added and subtracted only if they're fractions?
We can only add or subtract fractions if they have the same denominators
