Answer:
[tex]R = \frac{1}{6}[/tex]
Step-by-step explanation:
Given that she sold half the paintings and gives out one-third
Required
Determine the fraction left with her
The relationship between the paintings is as follows;
Sold Paintings + Giveaway Paintings + Remaining Paintings = 1
From the question;
Sold Paintings = 1/2
Giveaway = 1/3
Represent Remaining Paintings with R
Substitute these values in the above formula
[tex]\frac{1}{3} + \frac{1}{2} + R = 1[/tex]
Take LCM
[tex]\frac{2+3}{6} + R = 1[/tex]
[tex]\frac{5}{6} + R = 1[/tex]
Make R the subject of formula
[tex]R = 1 - \frac{5}{6}[/tex]
Take LCM
[tex]R = \frac{6-5}{6}[/tex]
[tex]R = \frac{1}{6}[/tex]
Hence, the fraction of the paintings left with her is [tex]\frac{1}{6}[/tex]
