I assume you're talking about multiplying the numerator and denominator by the same number in the case that you're trying to give two fractions common denominators. If you're multiplying 1/4 and 3/8 you first have to make them have a common denominator. The lowest common denominator would be eighths so you would multiply both the numerator and denominator of 1/4 by 2, which gives you 2/8. Then you would proceed to multiply both fractions together, Numerator x Numerator and Denominator x Denominator. The end result of this would be 6/64 which can be reduced to 3/32.

Why do you multiply numerators and denominators by the same number?
you have to multiply numerators and denominators because whatever you do to the bottom you have to do to the top
What do you do when you mutpiling fractions with common dennmonters?
Exactly the same as you do when multiplying fractions with different denominators. -- Multiply numerators . . . the product is the numeratore of the answer. -- Multiply denominators . . . the product is the denominator of the answer.
How do you subtract fractions with same denominators?
you subtract the numerators, and leeave the denomonators alone
When adding or subtracting fractions do you have to have the numerator the same or denominator?
The denominators must be the same, the numerators can be different.
When you add or subtract fractions with the same denominators what happens to the denominator in your answer?
It stays the same. Only the numerators change.
Why do you multiply numerators and denominators by the same number?
you have to multiply numerators and denominators because whatever you do to the bottom you have to do to the top
When cubed and squared are multiplied how do you get your product?
first you get the denominators the same then you multiply the number you multiplied to the denominator to the numerator then you add the two numerators together and keep the denominators the same then if needed you simplify

Exactly the same as you do when multiplying fractions with different denominators. -- Multiply numerators . . . the product is the numeratore of the answer. -- Multiply denominators . . . the product is the denominator of the answer.
How do you multiply fractions with like denominators?
The numerator and denominator of a product of fractions are simply the products of the numerators and denominators respectively. That is, a/b * c/d = (a*c)/(b*d). The denominators can be the same or different - that is irrelevant.
What is the process of subtracting fractions?
If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.
Why will the answer always be one when two numerators add up to the same number as two like denominators?
Yes because the numerators add up to equal a whole number which is 1
What If the denominator is not the same?
Multiply the denominators to equal numbers, then multiply by the same number for the numerator. Then solve.
IS THE LCD OF TWO FRACTIONS THE SAME AS THE LCM NUMERATORS AND FRACTIONS?
The LCD of two fractions is the same as the LCM of their denominators.
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.
How do you add fractions using the least common denomanator?
Ok. First you make sure the denominator (bottom number) is the same on all the fractions. The easiest way to do this is to multiply the denominators together, then multiply each numerator by the opposite fractions denominator. This is the easiest way to do this, you will simplify later. ONLY DO THIS IF THE DENOMINATORS ARE DIFFERENT. If they are the same just add the numerators together to get your fraction. Then simplify.
How do you add two fractions with the same denominator?
numerators you add, denominators you leave it the same
How do you subtract fraction if the if the numerators is the same?
You first have to convert the fractions so that the denominators are the same.
