Question

the sum of three consecutive integers is 147. use a tape diagram or equation to solve the three numbers. show your work

Answer 1

Let three be (x - 1), x and (x + 1).

The sum of three consecutive number is x, means that

`\begin{gathered} x-1+x+x+1=147 \\ 3x=147 \\ x=(147)/(3) \\ =49 \end{gathered}`

The value of x is 49.

Determine the two numbers.

`\begin{gathered} x-1=49-1 \\ =48 \end{gathered}`
`\begin{gathered} x+1=49+1 \\ =50 \end{gathered}`

So three consecutive numbers are 48, 49 and 50.
