4) The sum of three consecutive numbers is one hundred thirty - two. What is the smallest of the three numbers
with?

a = 43

b = 44

c = 45

the smallest of the three numbers is a = 43

a ; b ; c - numbers

b = a + 1

c = a + 2

a + b+ c = 132

replace b ; c

a + (a+ 1) + (a + 2) = 132

3a = 132 - 3

3a = 129

a = 129 : 3

a = 43

b = a + 1 = 43 + 1 = 44

c = a + 2 = 43 + 2 = 45

because they could drop even lower..
