### Difference

The

8, 9, 10, 11, and 12

The

Half this difference is 3

6 divided by 2 = 3

The

7 + 3 = 10

If you still don't understand this information try and solve these questions that we did during class.

1. What are the whole numbers between 68 and 72, 108.3 and 111.6

Answer : 69, 70, and 71 Answer : 109, 110, and 111

2. What number is halfway between the given numbers? a. 70 and 170 b. 1801 and 1813 c.18.4 and 6.2.

3. Is the number in the middle closer to the left number or the right number?

30/38/40 0.6/3.4/6.6 0.891/0.732/0.641 78.68/78.22/77.77

**"Whole Numbers"**that are**between**7 and 13 are :8, 9, 10, 11, and 12

The

**difference**between 13 and 7 is**6**Half this difference is 3

6 divided by 2 = 3

The

**number ID**is**halfway**between 7 and 137 + 3 = 10

**or**13 - 3 = 10If you still don't understand this information try and solve these questions that we did during class.

definitions

**Whole Number**- a whole number is a number without a decimal ; must also not have any place value below 0, for e.g. tenths, hundredths, thousandths, etc.

**Between**- anything in the middle of things. for e.g. my desk is between Diana and Kathryn in math.

**Difference**- how many numbers it takes to get from one number to another. 7 and 13 would be 6 because it goes 7,8,9,10,11,12,then 13, 6 numbers to get from one to the other.

**Halfway**- a word used to describe something that is divided into 2 equal parts.

Pictures drawn on paint by me, Credits to my cousin Alvin for showing me how to do this better. Thanks Alvin.
