Rewrite the expression ab dc ef such that each variable is replaced by a different non- zero digit and the value of expression is 1. (the answer may not be unique.)

ab dc ef is replaced by 12 43 56

Step-by-step explanation:

ab dc ef are replaced by the position they take when writing in an alphabetical order. a is 1, b is 2, c is 3, and so on.

So, ab dc ed is written as

12 43 56

and

56 - 43 - 12 = 1

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
