A proper fraction is a fraction such as 3/5, or 2/4, any fraction where the numerator is less than the denominator. Then it says "the whole is divided into an even number of equal parts, and an odd number of those parts exists." Such as 1 3/5. From my understanding, you then divide by 2, which would give you 0.8, which could then be turned into 0.4 if that's what your teacher wants you to do. In the end, there will be no odd number.

12C3 × 9C2
= 220×36
= 7920
Let the longer piece be x+5
Let the shorter piece by x
Both the wires together make 31cm so
x + x + 5 = 31
2x + 5 = 31
2x = 26
x=13
The shorter piece of the wire is 13cm.
<h3>Solution :</h3>
<u>Let x be the number</u>
