What is fraction?
Fractions are defined as a numerical figure that represents a portion of a whole. A fraction is a component or sector of any quantity taken from the whole, which might be a number, a specified value, or an item.
Now, according to the question;
The total number of the bars Conall initially had = 36
After he sells 10 bars on his own,
Total number of the bars remaining = Number of bars Conall had − Number of bars he sold on his own
Total number of the bars remaining = 36 − 10
Total number of the bars remaining = 26
Now, as his mother sold half of the bars;
Total number of the bars remained unsold = Total number of the remaining bars − Total number of the bars his mother sold
= 26 - 26/2
= 13
Total number of the bars remained unsold = 13
Fraction of Conall's bars that remained unsold = (Total number of bars remained unsold)/(Total number of bars Conall had)
= 13/36
Therefore, the fraction of Conall’s original 36 bars remained unsold is 13/36.
