What are the steps to comparing fractions?
Comparing fractions means looking at two fractions and figuring out which one is greater. To compare fractions, all you have to do is to make it so that they have the same denominator and then see which fraction has the greater numerator — this will tell you which fraction is greater.
How do you compare fractions with the same numerator?
So to compare fractions with the same numerator, all you have to do is compare the denominators. The fraction with the bigger denominator is smaller.
How do you compare fractions ks2?
Comparing unit fractions Since the numerator (top number) never changes with a unit fraction, you have to look at the denominator (bottom number) to compare two fractions. The bigger the denominator, the smaller the fraction! This is because if the denominator is higher, the whole has been split up into more parts.
How do you compare fractions BBC?
How are ratios similar to fractions how do they differ?
Ratio can show a give information about two or more items at a time. A fraction is simply some number divided by another number. A ratio is the relationship of two numbers, although it could be one number divided by another number. Fraction is the minimum form of the ratio.
How can I compare 2 fractions with the same numerator?
In the fractions having the same numerator, that fraction is greater which has the smaller denominator. If there are three or more fractions having the same numerator, they may be arranged in ascending (increasing) and descending (decreasing) order. The order will be in opposite order of denominators.
What are the strategies for comparing fractions?
If common denominators allow us to compare fractions just by looking at the numerators, then common numerators should allow us to compare fractions by looking only at the denominator. For this strategy to make sense, it is easiest to first compare unit fractions.[4]A unit fraction is a fraction with a numerator of 1.
How do you find the lowest terms in fractions?
Divide the numerator and denominator by the greatest common factor: This time, it takes only one step to get to the same result. To reduce a fraction to its lowest terms, divide the numerator and denominator by the greatest common factor.
How do you multiply a whole number into a fraction?
To multiply fractions by a whole number, you just multiply the numerator (top number) by the whole. Once you find that, divide the numerator by the denominator (bottom number), and you get a decimal version of the answer.
How do I estimate fractions?
To estimate fractions with mixed numbers, add the benchmark of the fraction to the whole number. Choose benchmarks for the fraction in the mixed number The benchmark is the reference for estimating the fraction.
