Explanation:

To write 0.4 in the form of a fraction p/q, you can express it as 4/10 because 0.4 is equivalent to 4 tenths. Now, simplify the fraction:

4/10 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2:

(4 ÷ 2) / (10 ÷ 2) = 2/5

So, 0.4 can be written as 2/5 in the form of a fraction. The sum of P and Q in this case is:

P + Q = 2 + 5 = 7
