Question

What would be a reasonable estimate for the value of w in this equation

7w = 90

12. 80. 100. 5.

Answer 1

If you divide 90 by 7 it equals 12.85, which is 12

Answer 2

12 would be sensible because when we divide 90 by 7 (isolating the variable to one side), we get 12.86, which is about 12.
