​

Answer 1

Explicație pas cu pas:

a*60=360

a=360÷60

a=6

6*60=360

70*x=280

x=280÷70

x=4

70*4=280

x*200=400

x=400÷200

×=2

2*200=400

200*x=200

x=200÷200

x=1

200*1=200

x÷40=8

x=40*8

x=320

320÷40=8

aici nu stiu ce e cu 450 si 90

900÷x=300

x=900÷300

x=3

900÷3=300

x÷500=1

x=500×1

x=500

500÷500=1
