Hello, Janet!

There are three consecutive multiples of nine.
The sum of the first two numbers is 2,853.
What are the integers?

A multiple of 9 is of the form: .9n, .for some integer n.

The first number is: . 9k
The next number is: . 9(k + !)

Can you set up the equation and solve it now?

A multiple of 9 is of the form: .9n, .for some integer n.

The first number is: . 9k
The next number is: . 9(k + 1)

What is the equation?

Janet, are you REALLY trying?
Problem states that 2 numbers = 2853;
Soroban tells you these 2 numbers are 9k and 9(k+1):
so equation is 9k + 9(k+1) = 2853 : now solve for k.
