Answer 2

Let's solve each of these expressions step by step:

2.a) 434 315 : 217 · 1000 : 225

First, let's break this down step by step:

434 315 ÷ 217 = 2000 2000 · 1000 = 2,000,000 2,000,000 ÷ 225 = 8,888.89 (rounded to two decimal places)

So, the result is approximately 8,888.89.

6. 14000 : 100 - 1418

14000 ÷ 100 = 140 140 - 1418 = -1278

So, the result is -1278.

B) 1000000 - 265378 - 81915 - 7347

1000000 - 265378 = 734622 734622 - 81915 = 652707 652707 - 7347 = 645360

So, the result is 645360.

r) 28 + 675 + 3247 + 96819

28 + 675 = 703 703 + 3247 = 3950 3950 + 96819 = 100769

So, the result is 100769.
