Question

if I say 5/8 in in Magna to take to make a desk magnet how many deaths magnets can be made 12 and 1/2 of a magnet tape

Answer 1

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,

`\begin{gathered} \text{ 1 magnet we make =}(1)/((5)/(8))\text{ desk magnet} \\ \text{ 1 magnet can make =}(8)/(5)\text{ desk magnet} \end{gathered}`

We need to find the number of desk magnet can make with the help of 12 1/2 magnet tape

`\begin{gathered} \text{ Since,} \\ \text{ With the help of 1 magnet tap we can make=}(8)/(5)Desk\text{ magnet} \\ \text{ then with the help of 12}(1)/(2)\text{ magnet tape we can make=12}(1)/(2)*(8)/(5)\text{ Desk magnet} \\ \text{ Simplify : 12}(1)/(2)*(8)/(5) \\ \text{12}(1)/(2)*(8)/(5)=((12*2)+1)/(2)*(8)/(5) \\ \text{12}(1)/(2)*(8)/(5)=(25)/(2)*(8)/(5) \\ \text{12}(1)/(2)*(8)/(5)=5*4 \\ \text{12}(1)/(2)*(8)/(5)=20 \\ \text{ Thus, } \\ \text{with the help of 12}(1)/(2)\text{ magnet tape we can make=20 Desk magnet} \end{gathered}`
