How would you use a number line to compare two fractions with different denominators?

You draw each of the fractions on the number line, and see which one is more to the right, i.e., greater. Please note that plotting the exact position of fractions this way is a bit imprecise - it is more exact to convert the fractions to a common denominator.

What is the definition to unlike denominators?
unlike denominators: the bottom number of a fraction. to have unlike denominators you must have two fractions with a different number on the bottom of each fraction.
What are fractions with unlike denominators mean?
The denominator is the bottom number in a fraction. Fractions like 1/3 and 1/4 have different numbers on the bottom. Those are unlike denominators.
How do you add two fractions with a different denominator?
You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.
How do you compare fractions that are not similar?
To compare fractions which are not similar, the fractions must be made similar by putting them over a common denominator. There are two similar ways of doing this:Find the lowest common multiple of the denominators. Multiply the first numerator by whatever number you multiply the first denominator by to get that multiple, and do the same with the second numerator and denominator. You can then compare the numerators.Multiply the first numerator by the second denominator, and the second numerator by the first denominator, and put both numerators over the product of the two denominators. You can then compare the numerators.
What is big 2 fourths or 1 fourths?
2/4 is greater than 1/4. When you compare fractions with like denominators, the greater numerator is the greater number.

How is multiplying fractions by a whole number is different from adding adding and subtracting fractions with like denominators?
Adding and subtracting fractions can ONLY be done if the denominators are the same; then the calculation is done by adding or subtracting the numerators. Multiplying (and dividing) fractions does not require the denominators to be the same. To divide by a fraction the divisor is inverted (the original numerator becomes the new denominator and the original denominator becomes the new numerator) and then the fractions are multiplied. Multiplying fractions is achieved by multiplying the numerators together AND multiplying the denominators together. A whole number is the same as a fraction with the whole number as the numerator and a denominator of 1, so when multiplying by a whole number the denominator is multiplied by 1 (leaving it the same) and the is multiplication is effectively just multiplying the numerator by the whole number.
How does using fraction strips with like denominators make it possible to add fractions with unlike denominators?
because they are the same number
How do you order factions from smallest to biggest?
get the common dinominators and do what u did to the denominator to the numerator!. ex: if I had three fractions with different denominators then I would multiply the denominators till they are the same number then with the number I multiplied with on the bottom I would multiply on to the top!
What must you find in order to add or subtract unlike fractions?
A common denominator. The best way is to find the LCM (Lowest Common Multiple) of all the denominators - the smallest number into which all the denominators will divide. (The easiest way to do this is to multiply all the different denominators together. Once this common denominator has been found, convert all the fractions into equivalent fractions with this new denominator.
When do you add fractions when baking?
In order to add fractions, they must have the same denominators. If the fractions you wish to add do not already have the same denominators, they can be made to do so by finding the right number by which to multiply both the numerator and the denominator of each fraction. To find this number, multiply all the distinct denominators together, then multiply both the numerator and denominator of each fraction by a number found by the dividing the product of the distinct denominators by the denominator of the particular fraction concerned. All the fractions will then have the same denominator. Add the numerators of such fractions together to find the numerator of the sum; its denominator will be the one common to all the fractions.
What is a fraction or mixed number whose denominators are powers of 10?
Although fractions or decimals are not called this, they are, in fact, decimal fractions.
What is the common denononator?
In fractions, the denominator is the bottom number. When adding or subtracting fractions, it is helpful if all the denominators are the same. To do this, we look for common denominators, which is the same process as finding the least common multiple.
