3. The sum of three consecutive numbers is 132. What is the smallest of the three numbers?
43 is the smallest of the 3 numbers
<em>calculation...</em>
<em>x + (x+1) + (x+2) = 132</em>
<em>3x + 3 = 132 -3</em>
<em>3x=129
</em>
<em>x=129/3
</em>
<em>
x=43 (answer for the 1st number)</em>
<em>43+1=44 (answer for the 2nd number)</em>
<em>43+2=45 (answer for the 3rd number)</em>
add them all to make sure they equal to 132
<em>43+44+45=132
</em>
<em>132=132</em>
4. Sandy sold half of her comic books and then bought 8 more. She now has 16. How many did she begin with?

Step-by-step explanation:
a) He can find the answer in one way
b) We make used of addition property of mathematics
c) The total number of blocks he is having is calculated as:
Blue blocks + Pink blocks + Green blocks
