The equation is part/whole = %/100 And if you plug numbers into that it would be 438000/561000 = x/100 Cross multiply leaving you with 43,800,000 = 561000x then divide them 43,800,000/561000 = 78.07 or 78.1
The inequality is: x < 90 ( or x is less than 90 ). Answers A and D are represented by: x > 90. Answer B is represented by: x = 90. Therefore this situation is: C ) A kiddie pool holds under 90 L of water.
