how do we fit a decimal between this pair 0.6____0.7

See my answer below.

I don't khow

To fit a decimal between the pair of numbers 0.6 and 0.7, you can use a process called "interpolation". Interpolation means estimating or finding values between two known values.

To begin, we need to determine how many decimal places we want to fit between 0.6 and 0.7. Let's say we want to fit only one decimal place between them.

To do this, we can divide the range between 0.6 and 0.7 into 10 equal parts since there are 10 possible digits (0-9) in a decimal place.

The first step is to find the difference between 0.6 and 0.7:

0.7 - 0.6 = 0.1

Next, divide this difference by 10 to find the size of each interval:

0.1 / 10 = 0.01

Now, we can add this interval to 0.6 to find the decimal that fits between them:

0.6 + 0.01 = 0.61

Therefore, the decimal that fits between 0.6 and 0.7 when fitting one decimal place is 0.61.
