### QUESTION 1 of 10

There are several ways to find the number exactly halfway between two given numbers.

We shall use two easy numbers, such as 60 and 70 to illustrate three different methods.

Method 1

Find the difference between the two numbers, which here is 70 - 60 = 10

Halve this difference, which here is 10 ÷ 2 = 5

Add this to the smaller number, which here is 60 + 5 = 65

Method 2

Find the difference between the two numbers, which here is 70 - 60 = 10

Halve this difference, which here is 10 ÷ 2 = 5

Subtract this from the larger number, which here is 70 - 5 = 65

Method 3

Find the mean of the two numbers by adding them together and halving the result.

The total is 60 + 70 = 130

Halve the result to get 130 ÷ 2 = 65

• Question 5

Write down the number which is halfway between:

5400 and 7400

6400
EDDIE SAYS
Find the difference between the two numbers, which here is 7400 - 5400 = 2000 Halve this difference, which here is 2000 ÷ 2 = 1000 Add this to the smaller number, which here is 5400 + 1000 = 6400
• Question 6

Write down the number which is halfway between:

5000 and 7400

6200
EDDIE SAYS
Find the difference between the two numbers, which here is 7400 - 5000 = 2400 Halve this difference, which here is 2400 ÷ 2 = 1200 Subtract this from the larger number, which here is 7400 - 1200 = 6200
• Question 7

Write down the number which is halfway between:

5000 and 9400

7200
EDDIE SAYS
Find the difference between the two numbers, which here is 9400 - 5000 = 4400 Halve this difference, which here is 4400 ÷ 2 = 2200 Subtract this from the larger number, which here is 9400 - 2200 = 7200
• Question 8
