Question

Q.3. Joselin reads for $\frac{1}{5}$ hour on the first day, $\frac{1}{4}$ on the second day and $\frac{1}{3}$ hour on the third day. If this pattern continues, how long will she read on the fifth day.

Answer 1

Dear Student,

$$\begin{gathered} FirstDayjoselinreads=\frac{1}{6}hours \\ seconddayshereads=\frac{1}{6}\times \frac{3}{2}=\frac{1}{4}hours \\ 3rdday=\frac{1}{4}\times \frac{4}{3}=\frac{1}{3} \\ 4thday=\frac{1}{3}\times \frac{5}{4}=\frac{5}{12} \\ 5thday=\frac{5}{12}\times \frac{6}{5} \\ =\frac{1}{2} \\ Henceon5thdayshestudies\frac{1}{2}hours \end{gathered}$$
