Question

Помогите пожалуйста ​

Answer 1

Ответ:

450 * 300 = 135000 147 * 2000 = 294000

180 * 700 = 126000 6800 * 60 = 408000

460 * 30 = 13800 7410 *60 = 444600

530 * 90 = 47770 230 * 400 = 92000

№ 4

630 / (3 * 3) = (630 / 3) / 3 = 210 / 3 = 70

300 / (3 * 25) = (300 / 3) / 25 = 100 / 25 = 4

(360 * 5) * 40 = 360 * (5* 40) = 360 * 200 = 72 000

4 * (6000 * 25) = 6000 * (4 * 25) = 6000 * 100 = 600000

50 * (2100 * 8) = (50* 8) * 2100 = 400 *2100 = 840000

450 000  / (15 * 10000 ) = (450000/ 10000) /15 = 45 / 15 = 3

450×300=135000

147×2000=294000

180×700=126000

6800×60=408000

450×30=13500

7410×60=444600

580×90=52200

230×400=92000

4)630:(3×3)=5670

300:(3×25)=4

(360×5)×40=2880

4×(6000×25)=600000

50×(2100×8)=840000

450000:(15×10000)=0,3
