If you apply it to the denominators, you could call it the least common denominator.

First you find a common multiple of the denominators. The least common denominator is handy but not essential. This number will be the denominator of the answer - before simplification.For both fractions find an equivalent fraction whose denominator is this common denominator.Carry out the subtraction on the new numerators to give the numerator of the answer.Simplify the result for the final, simplified answer.First you find a common multiple of the denominators.

Multiplying the denominators together of two or more unlike fractions will get you a common multiple.
The LCD for fractions is the LCM (least common multiple) of all of the denominators.
The least common denominator is the least common multiple of the denominators of the fractions.

It is usually called the least common multiple. But it can also be called the least/lowest common denominator when it is used for addition or subtraction of rational fractions.
Knowing the least common multiple of the denominators will help you find a common denominator when adding and subtracting unlike fractions. Knowing the greatest common factor of the numerator and the denominator will help you reduce the fraction if possible.
Generally speaking, if the question is about taking something away it is subtraction. If it is about a number of lots or copies or sets of something, it is multiplication.
I am assuming that denamintor is your way of spelling denominator. If not, please explain what it means and we can try to answer your question.The answer depends on what you wish to do. For multiplication or division it does not matter. For addition or subtraction you will need to find the least common multiple and rename the fractions so that their denominators are the same.
It is the lowest common multiple of the different denominators.
It shows multiple numbers in order to use in addition, subtraction, etc.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
Your question is a little confusing. If you are asking which gets done first ... addition/subtraction or multiplication/division ... the multiplication/division is done first. In other words, in 1 + 4 / 2, you divide 4 by 2 first, then add 1. So the answer is 3.
It will be easier to perform the required calculation.

To make 33 using the number 6, you can use multiplication and addition. For example, you can calculate (6 \times 5 + 3 = 30 + 3 = 33). Alternatively, you could use division, subtraction, or other operations involving multiple 6s combined with other numbers, but the simplest method involves basic arithmetic as shown.
