#n=3.3#

Explanation:

When a fraction is equal to another fraction, we can solve using the method of #color(blue)"cross-multiplication"#

#"That is " color(blue)(1.1)/color(red)(1.2)=color(red)(n)/color(blue)(3.6)#

To solve, multiply the #color(red)"red terms"# and the #color(blue)" blue terms"# together and equate them.

#rArrcolor(red)(1.2n)=color(blue)(1.1)xxcolor(blue)(3.6)#

#rArr1.2n=3.96#

To solve for n, divide both sides by 1.2

#cancel(1.2 n)/cancel(1.2)=3.96/1.2#

#rArrn=3.3" is the solution"#
