4 and 1/6 is the mixed number, or 4 and 2/12
Answer:
A. None of these
Step-by-step explanation:
The largest perfect square under 100 would actually be 81 (9 x 9)
90 and 99 are not perfect squares and 64 is smaller than 81.
' 36 = 9k ' is not an inequality. It's an <u>equality</u>, usually called an <em><u>equation</u></em>.
It's true whenever 'k' is 4, and false at any other time.
(You can determine that simply by dividing each side of the equation by 9.)
