Now we can express the rainfall in the first half of the month (7/8 inches) as a fraction:
Next, we will find the rainfall in the second half of the month by subtracting the first half's rainfall from the total rainfall:
Substituting the values we have:
To perform this subtraction, we need a common denominator. The least common multiple of 4 and 8 is 8. We will convert
Now we can perform the subtraction:
Finally, we can convert
So, the amount it rained in the second half of the month is:
