<em>Answer:</em>
The answer is 4 3/10
<em>Step-by-step explanation:</em>
If you first break this question up into two steps, you first must add the whole numbers and then the fractions, like this:
2 <u>7/10</u> 1 <u>6/10</u>
First, add the whole numbers [Bold]
2 + 1
That equals the whole number 3
2 <u>7/10</u> 1 <u>6/10</u>
Next you add the fractions [<u>Underlined</u>]
<u>7/10</u> +<u> 6/10</u>
this equals <u>13/10</u>
Since this fraction is higher than<u> 10/10</u>, it equals a whole number too. This fraction, <u>13/10</u>, will be <em>simplified</em> to 1 whole and <u>3/10</u>. After <em>simplifying</em> this number you add the whole numbers once again resulting in 3 + 1, giving you 4. after finding this out you add your<u> fractions</u> back in, creating the answer of 4 <u>3/10</u>.
Hope this helps you out!
