Answer 1

Решение и ответ:

$\displaystyle 2\frac{4}{{13}}+5\frac{2}{{13}}=\left({2+5}\right)+\left({\frac{4}{{13}}+\frac{2}{{13}}}\right)=7+\frac{{4+2}}{{13}}=7+\frac{6}{{13}}=7\frac{6}{{13}}$

Answer 2

To add the fractions 2(целых)4/13 and 5(целых)2/13, we need to add the whole numbers separately and then add the fractional parts separately.

Let's start with the whole numbers: 2(целых) + 5(целых) = 7(целых)

Now let's add the fractional parts: 4/13 + 2/13 = 6/13

Combining the whole numbers and the fractional parts, we get: 7(целых) + 6/13

Therefore, the sum of 2(целых)4/13 and 5(целых)2/13 is 7(целых)6/13.
