Question Here, a unit is divided into 5 equal parts. Write the fraction that gives the length of the pink lines in the respective boxes or in your notebook.
Here number line OT = 1 unit is divided into five equal parts OP, PQ, QR, RS and ST.
Hence length of pink line OQ = OP + PQ = \(\frac{1}{5}+\frac{1}{5}=\frac{2}{5}\)
Now, length of pink line OS = OP + PQ + QR + RS = \(\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}=\frac{4}{5}\)
Hence, OQ = \(\frac{2}{5}\) OS = \(\frac{4}{5}\)
