5 Multiple choice questions

  1. For all rational numbers a, b, and c, if a = b, then ac = bc
  2. Replace each variable in the expression by a given value and simplify that result.
  3. For each nonzero rational number a, there is one and only one rational number 1/a such that a * 1/a = 1. AKA: reciprocal
  4. For any number a,b and c,
    a + (b + c)= (a + b) + c
  5. This is a mathematical sentence that uses an equal sign to state that two expressions represent the same number or are equivalent.
