Question

Нужно решение, заранее спасибо

Answer 1

1. 3,452 + 17,23 + 1,548 = (3,452+1,548) + 17,23 = 5 + 17,23 = 22,23
    
2. 4 * 34,23 * 25 = (4*25) * 34,23 = 100 * 34,23 = 3 423

3. 54 271 + 39 999 + 10 001 = 54 271 + (39 999 + 10 001) = 54 271 + 50 000 =
     = 104 271

4. 56 + 56 + 56 + 56 + 56 + 740 + 740 + 740 = 56*5 + 740*3 = 280 + 2 220 =
     = 2 500

Answer 2

$1) 3.452+17.23+1.548=3.452+1.548+17.23=5+17.23=22.23 \\ \\ 2)4*34.23*25=4*25*34.23=100*24.23=3423 \\ \\ 3)54271+39999+10001=54271+50000=104271 \\ \\ 4) 56+56+56+56+56+740+740+740=56*5+740*3= \\ \\ =280+2220=2500$
