Squaring" means to multiply a number by itself. Squaring a positive number gets a positive result: (+5) × (+5) = +25. Squaring a negative number also gets a positive result: (−5) × (−5) = +25.
This is because to square a number just means to multiply it by itself. For example, (-2) squared is (-2)(-2) = 4. Note that this is positive because when you multiply two negative numbers you get a positive result.
You have to give them the same denominator so multiply 11/12 by 4 and 3/16 by 3. giving you 44/48 and 9/48. then divied 44 by 9 giving you 4.8888 there for there are 4 whole 3/16 sections of the 11/12 board
