Answer:

1) 2

2) -5

Step-by-step explanation:

It's always a great idea to use a number line when you are solving problems like these. In the first problem we are starting at positive 3, so go to the number 3 on the number line. Then we are adding a <em>negative </em>1, so we need to go back 1 on the number line. If we added a positive 1 we would need to go forward 1, but since this is a negative 1 we need to go backwards.

When you go back 1 from 3, you should get 2! Try this method for any other problem as well.

PLEASE HELP <br><br> I WILL BRAINLIEST !
jasenka [17]

Answer:

10 1/12

Step-by-step explanation:

In order to subtract fractions, you have to give them a common denominator.

18 1/2 can be rewritten as 18 6/12, as they are the same thing and 6/12 simplifies to 1/2. We make it 6/12 because we have to subtract it by 8 5/12, and the denominators are both 12.

So now we have 18 6/12 - 8 5/12, which gives us 10 1/12.
