Question : 35

Total: 40

Solution:

\;\text{ Number of pieces }\;=\;\frac{\;\text{ Length of string }\;}{\;\text{ Length of each piece }\;}

Before you divide make sure they are of the same unit. You can either change meter to centimeters or centimeters to meters then divide.

1\;\mathrm{m}=100\;\mathrm{cm}

3.6\;\mathrm{m}=3.6\times100\;\mathrm{cm}=360\;\mathrm{cm}

Number of pieces

=\;\frac{360\;\mathrm{cm}}{40\;\mathrm{cm}}=9

Note:

3.6\times100=3 .\overset{\frown}{6}\;\overset{\frown}{0} .=360
