How do you add #3\frac { 7} { 10} + 4\frac { 1} { 15} + 2\frac { 2} { 13}#?
Okay, so first you put all the fractions into a Common Denominator what this means is that all the bottom numbers have to be equal.
So let's add the first two numbers first
But we don't do anything to the whole number because it's not a part of the fraction! Therefore the numbers are going to look like
Which equals this is all just addition which I shouldn't be explaining
Now we do the next part
So we do the same thing we did above.
Which cannot be simplified!
Remember always simplify during tests or quizzes if you don't you will definite loose points; which is a frugal way to lose points after all that hard work.

The brackets are only there to highlight the grouping of numbers.
You can not directly add the 'counts' (numerators) unless the 'size indicators' (denominators) are all the same.
The last digit of 195 is 5 so 195 can not have 10 as a whole number factor. So lets try changing the 5 into 0

To add mixed numbers, follow these steps:

Convert each mixed number to an improper fraction. (3\frac{7}{10} = \frac{3 \times 10 + 7}{10} = \frac{37}{10}) (4\frac{1}{15} = \frac{4 \times 15 + 1}{15} = \frac{61}{15}) (2\frac{2}{13} = \frac{2 \times 13 + 2}{13} = \frac{28}{13})

Find a common denominator for all fractions. The least common multiple (LCM) of 10, 15, and 13 is 390.

Rewrite each fraction with the common denominator. (3\frac{7}{10} = \frac{37}{10}) (4\frac{1}{15} = \frac{61}{15}) (2\frac{2}{13} = \frac{280}{13})

Add the fractions together. ( \frac{37}{10} + \frac{61}{15} + \frac{280}{13} )

Convert the sum back to a mixed number if necessary. ( \frac{37}{10} + \frac{61}{15} + \frac{280}{13} = \frac{14261}{390} )

Simplify the fraction if possible.
After simplifying, if necessary, the sum will be in the form of a mixed number.

When evaluating a onesided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
