No.
No. Convert them to like denominators and add the numerators.
There is about 198 different nationalities in the USA
It depends what you are doing with the fractions. If you are multiplying or dividing fraction, the denominators do not need to be the same and the calculation can be carried out immediately. If you are adding or subtracting fractions, the denominators must be the same; if you have different denominators, the fractions must first be changed into equivalent fractions with the same denominator. When the denominators are the same (or have been made the same as equivalent fractions from being different) the calculation can be carried out.
Dissimilar fractions have different denominators.
Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.
You use them when there are 2 fractions with different denominators.
you make them have like denominators by multiplying so many times that they have the same denominators or you can make them have like denominators by multiplying the two
Are there peculiar ways different cultures or nationalities practice their faith?
They are not different.
Dissimilar fractions are fractions that have different denominators.
A fraction where the denominators are different EG: 1/6 and 1/4. Like fractions are when the denominators are the same EG: 1/6 and 2/6 Hope this helped :))))
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.
