Answer 3

Let's solve the expressions one by one:

(630+270:9):2=?

First, we need to solve the division inside the parentheses:

270 ÷ 9 = 30

Then, we add 630 and 30:

630 + 30 = 660

Finally, we divide by 2:

660 ÷ 2 = 330

So, the answer is 330.

Next, let's solve:

730-170+290 = ?

We need to start with the subtraction first:

730 - 170 = 560

Then, we add 290:

560 + 290 = 850

So, the answer is 850.
