[tex]\blacksquare \ \ \boldsymbol{N=60}[/tex]
[tex]\pmb{\cal{SOLUTION:}}[/tex]
Hi there!^^ The skill required for this problem is cross-multiplying; it's the way proportions are solved.
[tex]\to\boldsymbol{\dfrac{2}{4} =\dfrac{N}{60}}[/tex]
(We cross-multiply: 2 * 60 and 4 * N)
[tex]\to\boldsymbol{2*60=4*N}[/tex]
[tex]\to\boldsymbol{120=4N}[/tex]
Next I divide both sides by 4 to find N.
[tex]\to\boldsymbol{N=30}[/tex]
I hope I've made the concepts clear enough for you!
