if I say 5/8 in in Magna to take to make a desk magnet
i.e 5/8 magnet require= to make 1 desk magnet
Thus,
[tex]\begin{gathered} \text{ 1 magnet we make =}\frac{1}{\frac{5}{8}}\text{ desk magnet} \\ \text{ 1 magnet can make =}\frac{8}{5}\text{ desk magnet} \end{gathered}[/tex]We need to find the number of desk magnet can make with the help of 12 1/2 magnet tape
[tex]\begin{gathered} \text{ Since,} \\ \text{ With the help of 1 magnet tap we can make=}\frac{8}{5}Desk\text{ magnet} \\ \text{ then with the help of 12}\frac{1}{2}\text{ magnet tape we can make=12}\frac{1}{2}\times\frac{8}{5}\text{ Desk magnet} \\ \text{ Simplify : 12}\frac{1}{2}\times\frac{8}{5} \\ \text{12}\frac{1}{2}\times\frac{8}{5}=\frac{(12\times2)+1}{2}\times\frac{8}{5} \\ \text{12}\frac{1}{2}\times\frac{8}{5}=\frac{25}{2}\times\frac{8}{5} \\ \text{12}\frac{1}{2}\times\frac{8}{5}=5\times4 \\ \text{12}\frac{1}{2}\times\frac{8}{5}=20 \\ \text{ Thus, } \\ \text{with the help of 12}\frac{1}{2}\text{ magnet tape we can make=20 Desk magnet} \end{gathered}[/tex]
