Answer 1

Ответ:

300 : 20 = (200+100):20=200:20+100:20=10+5= 15

680 : 2 = (600+80):2=600:2+80:2=300+40= 340

600 : 5 = (500+100):5=500:5+100:5=100+20 = 120

480 : 40 = (400+80):40=400:40+80:40=10+2= 12

13×5 = (10+3)×5=10×5+3×5=50+15 = 65

240 : 4 = (200+40):4=200:4+40:4=50+10 = 60

500 : 20 = (400+100):20=400:20+100:20=20+5 = 25

900 : 2 = (800+100):2=800:2+100:2=400+50=450

Пошаговое объяснение:

$1)300 : 20 = (200+100):20=200:20+100:20=10+5= 15\\ 2)680 : 2 = (600+80):2=600:2+80:2=300+40= 340\\ 3)600 : 5 = (500+100):5=500:5+100:5=100+20 = 120\\ 4)480 : 40 = (400+80):40=400:40+80:40=10+2= 12\\ 5)13*5 = (10+3)*5=10*5+3*5=50+15 = 65\\ 6)240 : 4 = (200+40):4=200:4+40:4=50+10 = 60\\ 7)500 : 20 = (400+100):20=400:20+100:20=20+5 = 25\\ 8)900 : 2 = (800+100):2=800:2+100:2=400+50=450$

Answer 3

300 : 20 = (15) + 680 : 2 = (340) 600 : 5 = (120) 480 : 40 = (12) 13 × 5 = (65) 240 : 4 = (60) 500 : 20 = (25) 900 : 2 = (450)
