Question about The Learning Company Achieve! Math & Science Grades 1-3 (381933) for PC, Mac
Let the three consecutive numbers be x, x+1, x+2.
Now, the smallest is 57 less than three times the largest...
=> x + 57 = 3(x + 2)
=> x + 57 = 3x + 6
=> 2x = 57 - 6
=> 2x = 51
=> x = 25.5
=> x, x+1, x+2 = 25.5, 26.5, 27.5
So, the three consecutive numbers are 25.5, 26.5, 27.5.
