a. We are told that 3/5 of the devotional books are bible storybooks.
Also, he will move to the display table 1/2 of that fraction.
So, to find the final fraction part of the children's devotional books he moves, we need to find 1/2 of 3/5.
So, we need to multiply the fraction 1/2 by the fraction 3/5:
[tex]\frac{1}{2}\cdot\frac{3}{5}=\frac{1\cdot3}{2\cdot5}=\frac{3}{10}[/tex]
Thus, the fraction part is
[tex]\mathbf{\frac{3}{10}}[/tex]
b. Now, notice that the total of devotional books is 100. So, we need to find 3/10 of 100. We do so by multiplying that fraction by 100:
[tex]\frac{3}{10}\cdot100=3\cdot\frac{100}{10}=3\cdot10=30[/tex]
Therefore, the number of bible storybooks he moved to the display table is 30.
