What is halfway between the decimal numbers 3.4 and 3.7?

Answer 1

3.55

3.7 - 3.4 = 0.3

0.3 / 2 = 0.15

3.4 + 0.15 = 3.55

3.7 - 0.15 = 3.55

* The simplest way to find a halfway point (which is also the average), is to add the numbers together and divide by 2. 3.4 + 3.7 = 7.1 and 7.10 / 2 = 3.55
