In this case, we take the (least common multiple) LCM of their denominators and express each of the given numbers with this LCM as the common denominator then you can add/subtract its numerators.
2. You simply multiply the nominators and the denominators. After this, you might have to simplify if asked to do so.
3. First, you should take the reciprocal of the divisor then multiply its inverse to the dividend.
4. Write the problem in a vertical format where the decimal point is always aligned. This will make sure that the digits with the same place value are in the right place. And lastly, solve the equation from right to left.
5. First, line up the numbers to get ready to multiply. Next, multiply each digit in the top number by each digit in the bottom number, just like whole numbers. Then, place the decimal point in the product by counting the number of decimal places in each of the numbers that were multiplied.
6. You gotta convert the divisor first into a whole no. Move the decimal point of the divisor to the right until it becomes a whole number then move the decimal point of the dividend in the same position you moved the divisor, or you may just multiply both of them in the power of ten. Then you can successfully divide it easily.

1. When given numbers have the same denominator:
Just simply add/subtract its numerators.
When given numbers have different denominators:
