Answer 1

Answer:

the integers are consecutive, each is one more than the last. That means our first integer is 4 . Our second integer is 4+1 , or 5 , and our third integer is 5+1 , or 6 . Our answer is confirmed because 4+5+6=15 .

Answer 2

Let the smallest number be x.

Middle number = ( x + 1 )

Largest number = ( x + 2 )

x + ( x + 1 ) + ( x + 2 ) = 15

3x + 3 = 15

3x = 15 - 3

3x = 12

x = 12/3

x = 4

Smallest number = 4

Middle number = ( 4 + 1 )

= 5

Biggest number = ( 4 + 2 )

= 6

Hence, the numbers are 4,5 and 6 respectively.
