Answer 1

1. (6/5+2.8)×100= (1.2+2.8)×100= 4×100 = 400

(20000+40000):100 = 60000:100= 600

2.3(8×25+100) = 3×(200+100) =3×300=900

3. 0.5*(19/7+30/7) = 0.5×(49/7) = 0.5×7=3,5

4. 3×8÷10 = 24÷10=2,4

4×5×13×0.01 = 20×13×0.01 =260×0,01 = 2.6

5. 16×3×625= 48×625 =30000

6. 0.001×32×3125= 0.032×3125=100

7. 32×125×17÷1000 = 4000×17÷1000=68000÷1000=68

8. 125×4=500

9. 8×3×25=24×25=600
