What number is halfway between 1.4 and 2.1?
To calculate the answer, first we can find the difference between 2.1 and 1.4, which is 0.7. We’re looking for the number which is halfway between these two numbers. To find the number which is halfway between 1.4 and 2.1, we need to half the difference. Half of 0.7 is 0.35. So if we add 0.35 to 1.4, that will give us our answer. 1.4 plus 0.35 equals 1.75. The number which is halfway between 1.4 and 2.1 is 1.75.
