What To add or subtract fractions with different denominators first find equivalent fractions with what?
To add or subtract fractions with different denominators, first find equivalent fractions by determining a common denominator. This typically involves finding the least common multiple (LCM) of the denominators. Convert each fraction to an equivalent fraction with this common denominator, and then you can add or subtract the numerators while keeping the denominator the same. Finally, simplify the resulting fraction if possible.
How do you subtract fractions without alike denominators?
Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.
How do you subtract fractions when denominator is different?
By finding the lowest common denominator of the fractions.
What strategies can I use to add and subtract fractions and decimals?
To add and subtract fractions, first ensure they have a common denominator by finding the least common multiple (LCM) of the denominators. Once the fractions have the same denominator, you can add or subtract the numerators while keeping the denominator unchanged. For decimals, align the numbers by their decimal points, and then perform the addition or subtraction as you would with whole numbers. Lastly, ensure to simplify the result if necessary, especially for fractions.

When adding or subtracting two fractions with denominators that are not equal what is the first step you take?
When adding or subtracting fractions with different denominators, the first step is to find a common denominator. This involves finding the least common multiple (LCM) of the two denominators. Once you have a common denominator, you can then add or subtract the numerators of the fractions accordingly.
How can the greatest common factor and least common multiple help you work with fractions?
Finding the GCF of the numerator and the denominator of a fraction and dividing them both by it will give you the simplest form of that fraction. Finding the LCM of unlike denominators and converting them to it will make it possible to add and subtract unlike fractions.
What is the first step to finding the lowest common denominator of two fractions?
The first step in finding the lowest common denominator of two fractions is to multiply the two denominators. Then you see if there are any smaller numbers that are divisible by both denominators.

Lastly, ensure to simplify the result if necessary, especially for fractions.
Why do denominators have to be the same when you add or subtract fractions?
Denominators must be the same when adding or subtracting fractions because fractions represent parts of a whole, and only like parts can be combined accurately. When the denominators differ, the fractions represent different-sized pieces, making it impossible to directly combine them. By finding a common denominator, you ensure that the fractions are expressed in terms of the same whole, allowing for correct addition or subtraction of their numerators.
