Question

8. Вставь вместо число. a) 7.3=7+7+7=→21:=7 б) 9.2 9+9=:2=9 :7=3 18:=2​

Answer 1

Ответ:

7×3=7+7+7=21. 21÷3=7. 21÷7=3

9×2=9+9=18. 18÷2=9. 18÷9=2

Answer 2

a) 7.3 = 7 + 7 + 7 = 21 : 7 = 3 b) 9.2 = 9 + 9 = 18 : 2 = 9 : 7 = 1.2857 (rounded to 4 decimal places)

Please note that the second equation in part b) seems to have an error. If you provide more information or clarify the equation, I can help you solve it correctly.
