Question

Сложите 2/5 от 45 и 2/5 от 30

Answer 1

45*(2/5) + 30*(2/5) =18 +12 =30

Answer 2

To find the sum of $\frac{2}{5}$ of 45 and $\frac{2}{5}$ of 30, you simply calculate each of these values and then add them together.

$\frac{2}{5}$ of 45 is $\frac{2}{5} \times 45 = \frac{2 \times 45}{5} = \frac{90}{5} = 18$.

$\frac{2}{5}$ of 30 is $\frac{2}{5} \times 30 = \frac{2 \times 30}{5} = \frac{60}{5} = 12$.

Now, add these two results together:

$18 + 12 = 30$.

So, the sum of $\frac{2}{5}$ of 45 and $\frac{2}{5}$ of 30 is 30.
