Before adding or subtracting two fractions they are converted into like fractions. Explain with examples why this is necessary.
They have to have the same denominator.
because fact families are like this 2+2=4,4-2=2 and adding
When adding or subtracting fractions with different denominators, it is necessary to find a common denominator to solve the equation. A common denominator is like a common multiple, except its function is as the bottom number in a fraction.
subtracting similar fractions is just like adding them. You only subtract the numerator (top part) and then copy the denominator (bottom part). 4/5 - 1/5 = 3/5
What is the definition of Adding and Subtracting Like Fractions
Before adding or subtracting two fractions they are converted into like fractions. Explain with examples why this is necessary.
You need a common denominator for both.
They have to have the same denominator.
Buying pizza and eating it.
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.
Knowing the LCM will help when adding or subtracting unlike fractions. By finding the LCM of the denominators, (called the lowest common denominator) you can convert unlike to like fractions and proceed with the adding or subtracting. Knowing the GCF helps reduce a fraction. By finding the GCF of the numerator and the denominator and dividing both of them by it, you can reduce a fraction to its lowest terms (simplest form). If the GCF is 1, the fraction is in its simplest form. You can successfully multiply fractions without knowing the GCF or LCM.

Because think of like fractions as the same things.. you can subtract halves from halves for example, but what does it mean to take away a half from a third?By converting them into like fractions, we can add or subtract them easily.
Adding and subtracting polynomials is simply the adding and subtracting of their like terms.
