Question

The number of students in Damonte's class, 35, is greater than the number in Rose's class by 12. How many students are in Rose's class?

Answer 1

There are `23` students in Rose's class.

Explanation:

Lets give the number of students in each class a variable

Number of students in Damonte's class `= x`
Number of students in Rose's class `=y`

In an equation, that would be:

`35-12=y`

Because there are `12` students less in Damonte's class than in Rose's class.

`35-12=y`
`23=y`

There are `23` students in Rose's class.

Double check:

`23+12=35`

Answer 2

`23`

Explanation:

Look at what you know (data given), what you want to know (Rose's class size), and then what you need to get from one to the other.
Diamonte's Class Size = 35
It is greater (more) than Rose's class by 12. SO, Rose's class must be 12 LESS than Diamonte's class:
`35 - 12 = 23`
