Answer 1

7) 100×5:100+500×2:100> 1000:100:2-240:60

500:100+1000:100 >100:2-40

50+100 >50-40

150 > 10

263 000-(305 221-60 636)+88:2> 36×(5000-4500)-24×0-217:7

263 000-244 584+44 >36×500-0-31

19 416+44 >1800-0-31

19 460 > 1769

8) 9270+a=13 601 c×900=30 600

a=13 601-9 270 c=30 600:900

a=4 331 c=34

450+456:8+50×50-e=2000

450+57+2500-e=2000

507+2500-e=2000

3007-e=2000

e=3007-2000

e=1007

b-303 220=347 346

b=303 220 +347 346

b=650 566

125:d=31(rest 1)

d=(125-1):31

d=124:31

d=4

5×f-(926-203×3)-12=500

5×f-(926-609)-12=500

5×f-317-12=500

5×f-305=500

5×f=500-305

5×f-195

f=195:5

f=39
