0.186 is the answer to your question!
Step-by-step explanation:
A mixed number consists of an integer and a proper fraction:

where the numerator is less than the denominator (b < c).
A terminating decimal is a decimal that ends. For example, 1/2 = 0.5.
A repeating decimal is a decimal that repeats forever. For example, 1/3 = 0.33333...
You must use 2, 3, and 4 exactly once. Try different combinations and see which ones result in a terminating decimal, and which one results in a repeating decimal.
$4.08
Explanation:
That would be a lot of addition, and $4 and 8 cents.
Since $1+$2= $3
2 d + 3 q = 95c
95c + 13c = $1.08
$1.08 + $3 = $4.08
There are 8 black socks and 20 white socks. 5 socks times 4 = 20 white socks, and 2 socks times 4 = 8 black socks. So, Pa has 8 black socks.
